Ignore Vim untitled and unsaved buffer swapfiles

This repository didn't have a CONTRIBUTING.md file. Now it does.

Per discussion in #148.

Unignore "packages/*/build" in VisualStudio.gitignore.

Vim creates buffer swapfiles starting at .swp for buffers that are
active but untitled and unsaved.

Updated to exclude *.publishsettings

Erlang.gitignore erlang.crash.dump added

More pr consolidation

Update VisualStudio.gitignore for vs 2012 web deploy setting.

Visual Studio 2010 Express for Windows Phone seems to generate .cachefile files.

If you use package restore, you actually don't want this file
included. It's not needed. It's only needed if you version
packages. AKA, you only need this file if you are not ignoring
the "packages" folder.

Dotnet gitignore pr consolidation

I agree to ignore the NuGet packages folder, but I really think you should check in the repositories.config so NuGet PackageRestore can do it's magic when someone pulls the code and tries to build it...

Add trailing slashes to folders, RS rule comment, remove dupes.

This might be created temporarily during a build.

VS2012 creates UpdateLog2.htm - not needed in git repository

New web deploy file name? vs 2012 added this to my solution and it shouldn't go to an open repo.

Consolidate CSharp and VB.NET gitignore files into VisualStudio one.

Cross platform .NET Dev FTW!

Added __pycache__

Rename Wordpress.gitignore to WordPress.gitignore

WordPress should *always* have a capital P!

Workspaces are real documents that can be opened, just like `xcodeproj`
documents. These documents are also generated/used by CocoaPods to
configure a project’s dependencies. For these reasons, there does not
seem a good reason to ignore these any longer.

add a CONTRIBUTING.md file, copied verbatim from the "Pull Requests" section in README.md

These files were redundant. They had almost exactly the same
settings. They are being replaced by the VisualStudio file.

The VisualStudio gitignore file was missing a few useful
settings contained in the CSharp and VB.NET gitignore files.

  add intellij files to Android.gitignore
