CheckIO: fixed handling of unknown types. Ticket #5051
Add VS2012 projects for my personal use (using /LTCG, /MP, /RELEASE, /MT)
Add a script to run coverity with VS2012.
Move astyle options to astyle.ini.

This way we can use it in runastyle and runastyle.bat.
Settings changes:
* specify the files to exclude instead of specifying the files to style
* remove `--lineend` option
* keep the file's modified timestamp
* only show the styled files on the command output

Also change the astyle version check to only check for older not the exact version.
Update runastyle.bat from MPC-HC.

It includes a check if astyle is present and for astyle's version.
Also, it allows drag and dropping files onto it to style them.
Run node make
Update .mailmap.
