IndentationSize and ConvertTabsToSpaces settings can now be defined in separate policies together with other formatting options.
Tried implementing automatical updating of editors after changing policy-specific indentation changes + some refactoring.
Fixed CSharpBinding tests.
Redesigned replacement of editor options by language binding, now all C# code editors are updated, when changing IndentationSize or ConvertTabsToSpaces options in any policy.
Corrected reverting of editor options when C# binding's editor extension is detached.
Merge branch 'csformatter' to 'master'.
