Continuation of https://github.com/github/gitignore/pull/594/ and details from http://support.microsoft.com/kb/211632

Intellij's iml file can be anywhere on the path.
This is true for multi-module maven project where each module has its own $projectName.iml file in its own directory.

These are relatively new, the crashlytics.properties file contains the secret and can [alternatively](https://plus.google.com/+AntonioBertucci/posts/S9krjvXfgfm) contain the apikey to rid your repo of the extra strings file.

The .settings folder contains all of the user-specific preferences for Momentics (like it does for Eclipse, since they're the same underneath). Should be local only.

This .gitignore now ignores everything that build clean gets rid of

As described on https://docs.python.org/dev/library/venv.html#creating-virtual-environments

The template hasn't been touched since it was added to this collection.
There are some problems with it - mainly that it's hard to know if these
rules are all still relevant, and the large prose block is probably more
confusing than helpful here.

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.
