Updated format string highlighting and fixits to take advantage of the new CharSourceRange class.
- Change HighlightRange to allow highlighting whitespace only in a CharSourceRange (for warnings about the ' ' (space) flag)
- Change format specifier range helper function to allow for half-open ranges (+1 to end)
- Enabled previously failing tests (FIXMEs/XFAILs removed)
- Small fixes and additions to format string test cases

- Precision toStrings shouldn't print a dot when they have no value.
- Length of char length modifier is now returned correctly.
- Added several fixit tests.
Note: fixit tests are currently broken due to a bug in HighlightRange. Marking as XFAIL for now.

- Added some handling of flags that become invalid when changing the conversion specifier.
- Changed fixit behavior to remove unnecessary length modifiers.
- Separated some tests out and added some comments.

- Refactored LengthModifier to be a class.
- Added toString methods in all member classes of FormatSpecifier.
- FixIt suggestions keep user specified flags unless incorrect.
Limitations:
- The suggestions are not conversion specifier sensitive. For example, if we have a 'pad with zeroes' flag, and the correction is a string conversion specifier, we do not remove the flag. Clang will warn us on the next compilation.
