Fix Mixed Tabs

This is an extension for Visual Studio 2010 that detects and offers to fix mixed tabs and spaces.  If it detects mixed tabs and spaces whenever you save or load a file, it displays a margin in the editor with options to tabify or untabify the entire file.  It also has options to never show again (for a file for that run of VS), and it can be closed or ignored so that it won't have any effect.

See my blog at http://blogs.msdn.com/noahric for more information about my extensions and writing your own editor extensions.

Version history:

v2.3 - VS2013 support and fixed "Don't show again" to at least hide the information bar. It doesn't hide anything permanently, still.

v2.2 - VS2012 support.

v2.1 - Fix issue where the information bar keeps showing up even though tabify has no effect.  Also workaround an issue in the VS editor where the built-in tabify/untabify operations make many more edits than are necessary, which causes perf issues on large files with few lines to tabify or untabify.

v2.0.2 - Reduced timer for showing the margin to 175 ms in rich-client experience (courtesy Steven Schermerhorn).

v2.0.1 - Actually updated for RC/RTM.  v2.0 had a CopyLocal reference to a dll that has been removed in the RC, so the extension actually wasn't working at all.

v2.0 - Updated for RC/RTM.

v1.0 - Initial submission to VS Gallery
