Fixed #5863 (False positive: array index is used before limits check)
#4375 New check: add style warning about 'double d=false;' Add a new check to CheckBool. Also implement Variable::isFloatingType()
Stabilized AST:
- Fixed broken simplification causing crashs when cast was followed by unary minus (real world examples from arch/parisc/math-emu/ (linux-kernel))
- Stabilized determination of unary and binary operators
CheckBool::checkAssignBoolToFloat() - don't crash on unknown variables
Fixed TODO in checkAssignBoolToFloat
Fixed crash on complex cast.
Link to IRC channel instead of just mentioning it.

Add VS2013 projects for my personal use (using /LTCG, /MP, /RELEASE, /MT).

[ci skip]
Add a script to run coverity with VS2013.

[ci skip]
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.

[ci skip]
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.

[ci skip]
Remove multiple newlines.

[ci skip]
Tweak sorttable.js.
