Comments

Just added some comments. Some of us don't need some of the lines in the file.

Remove `build/` suppression

Exclude Latexian temp files for Tex documents

Include lib64 for virtualenv

Latexian adds some additional temporary files, which are not required for building the project. Therefore they are better left out as well

On systems that require a lib64, virtualenv creates a symlink to the local lib.

Add TeX precompiled preamble and xypic

Ignore ApplicationInsights.config for Microsoft Azure

A precompiled header(`latex -ini`) compiled creates a `.fmt` file.
To speed up xypic's drawing, precompiled matrices are created with the `\CompileMatrices` entry in the preamble. This creates `*.xyc` files.

Fuse hidden

Update Eclipse.gitignore

Remove .gradle because it is not eclipse specific and already added in Gradle.gitignore.

Windows Azure -> Microsoft Azure. Due to https://azure.microsoft.com/sv-se/blog/upcoming-name-change-for-windows-azure/

Ignore Azure ApplicationInsights.config in VisualStudio.gitignore

Stop ignoring StyleCop.json

The authoring of NuGet packages quite often include `build` folders, and when this is .gitignore'd it's very often the source of bugs in files that don't get checked in.

I've never seen a Visual Studio project that builds to a `build` folder (`bin` is the default name). As this is a Visual Studio template file, and we have real projects that include `build` folders that include source code, I recommend we remove suppression of this folder.
