* Handle flawfinder severity level
* Reverted code allowing Flawfinder to piggyback off of gcc's format handler
* Gave Flawfinder its own format handler and made requested changes.
* Flawfinder support added for C and C++
A minor modification to gcc handler was made to support flawfinder's
single-line output format that does not have a space following the
colon denoting the warning level. gcc handler still passes its
Vader tests after this modification.
* Documentation fixes
* Revert documentation regression
* Added Flawfinder to table of contents
* Removed trailing whitespace
* Follow ALE conventions better
Added additional documentation and Vader tests
