Found via UBSan, actual (sample) error:
"plugins/text-freetype2/text-functionality.c:284:26: runtime error: left
shift of 194 by 24 places cannot be represented in type 'int'"

Calling [NSString stringWithUTF8String:] with NULL causes it to raise an
exception: +[NSString stringWithUTF8String:]: NULL cString

In my recent update to add a "show" button to the passworded text
property, I neglected to connect the edit widget to
WidgetInfo::ControlChanged, so it isn't able to detect when the text is
changed by the user.

libcurl-dev added for debian compile guide

Recently libcurl was added as a required dependency, but it was not
updated for the debian install instructions

Fix required packages for Fedora

Tried to build on Fedora 21, complained about missing libcurl-devel.

On mac, pkg-config by default expects "libcurl" rather than "curl"

Allows the user to be able to optionally toggle the password text if
they wish.  Mostly useful for troubleshooting purposes.

Qt5Network has been replaced by libcurl.

The Qt5Network classes seem to only support OpenSSL, and because OpenSSL
isn't available on windows, we would have to distribute it with the
program to get SSL access working.  The problem with that is that
OpenSSL is not GPL-compatible, so we cannot distribute OpenSSL with the
program, which means we have to find a better (and preferably superior)
library for accessing remote files that can use the windows SSPI for our
SSL needs, which comes with the operating system.

Fortunately, libcurl is probably the best library out there, and can be
compiled with SSPI instead of OpenSSL, so we're just going to switch to
libcurl instead.  Originally I thought it didn't support SSPI, otherwise
I would have implemented it sooner.

As a side note, this will make it so we'll able to get files from the
internet via plugins, which will be quite useful.

The RemoteTextThread class is a QThread that is used to get text
remotely in a separate thread with libcurl.  This is intended to replace
the Qt5Network classes because of their dependency on OpenSSL, which we
can't distribute.

This makes it easier to set BUILD_TESTS (introduced in
87ea0392) from ccmake/cmake-gui

Reduces required scrolling when lots of new audio sources are added
(e.g. aux devices being enabled in the same dialog) when the dialog
was opened with just a few audio sources being present. Unfortunately,
the "restart required" warning is pushed all the way to the bottom
even if the source list is empty

The screen index returned from XDefaultScreen is 0-based, and we were
decrementing it before the check to see if it had reached 0 rather than
after, so in the default_screen function it would always end up getting
either the wrong screen or no screen.

When xcb_query_pointer and xcb_query_pointer_reply was called with no
valid screen, it would fail with an error, thus making it so that the
mouse buttons could not be properly captured as hotkeys.

This probably fixes the crash from "libobs: Check effect mutex exists
before destroying it" (c2c47b11)

This reverts commit c2c47b11.

Fixes a crash if graphics system didn't finish intializing.

This should allow entering alt + numpad N (N > 0) on windows since there
doesn't seem to be a way to completely ignore input events generated
from "alt codes"

This is just for visuals, no functionality change

Removed code where if a PTS diff was greater than a certain
threshold it was forced to the previous PTS diff.  This breaks
variable length frame media like GIF.

This prevents odd behavior with Qt5.4 turning the rounded buttons
into square push buttons.

UI supplied per scene hotkey to allow switching between scenes; this
has to be done in the UI since it's up to the application to define
what exactly "changing/selecting a scene" means (changing the output
of channel 0 may not be enough for other applications)

OBSHotkeyEdit is similar to QKeySequenceEdit, except less terribad on OSX, while
OBSHotkeyWidget provides a container that automagically encapsulates multiple
bindings per hotkey

OBSHotkeyLabel in combination with OBSHotkeyWidget provides mechanisms for
dealing with hotkey pairs (see upcoming usage in window-basic-settings.cpp)
