Amends #1165

Ignores *.lyx~ (crash recovery) and *.lyx# (timed autosave) files generated by LyX - the document processor.

guess that root iml needs to be ignored and others need to be shared

removed the iml filter - this is my current best understanding of the docs, but I'm still unsure

To clarify when to ignore/include *.imls as per https://intellij-support.jetbrains.com/entries/23393067

also added optionals from the same

Amends #1084

arm-p is another compiled output folder, for device-profile builds

Ignore debug/release builds (those go in Releases)

Fixes #1090 - this is the part of that PR that seems justified.

Amending #1072

When working with multifile LaTeX-documents in AUCTeX in emacs, it creates the auto-folder to keep track of styles, macros etc. in the whole document. Unnecessary of versioning purposes.

Reftex adds these for internal processing, only auxillary files for composition and compilation of tex-documents.

xcuserstate files are generated from within Xcode and saved in your project bundle to remember your last opened file, the open state of any group folders, open tabs, and any other user setting your project might need to remember, this is something that shouldn't be tracked in version control

Updated to include 'bin-release' folder, another folder for generated binary builds

Remove unnecessary wording about negative ignore rules.

This commit adds a global ignore file for SlickEdit, a commercial editor.

SlickEdit will create the following files when the user sets up a workspace:

*.vpw       Workspace file. Contains a list of project files associated with
            the workspace.
*.vpj       Project file. Contains the project’s settings, including the list
            of source files.
*.vpwhist   Workspace history file for Windows. Contains user session
            information (list of open files, debugger breakpoints, etc.)
*.vpwhistu  Workspace history file for UNIX/Linux/MacOSX. (Same as above.)
*.vtg       Workspace tag file. Contains a database of source code symbols.

It is assumed that GitHub users will generally not want to store their
workspace and project files in a repository, so those files are ignored
globally.  However, those files do not contain user-specific data so they
could be stored in a repository and shared among developers if desired for
a particular project.  This can be done by adding rules like ’!*.vpw’ and
‘!*.vpj’ to the project’s .gitignore file.

The workspace history and tag files contain user-specific data, so they
should not be stored in a repository.

Note: The user guide is 1400 pages long and over 13MB in size.

Searching for ‘vpwhist’ will lead to the section that discusses storing
these files in a repository.

Dolphin, the KDE file manager, writes specific directory configuration in .directory files.
