Tweaked Joomla signatures to look for the administrator directory
instead of a file in the root directory.
This will help limit false positives due to plugins containing
copy-pasta garbage.
The whole Joomla signature structure needs to be rethought, getting
false positives even after a successful match.
Added exclude to oscommerce2 signatures for loaded7.
Added admin directory to oscommerce2 to ensure that we are not dealing
with plugins.
Added ugly logic to vercomp function to remove alpha / beta from the
version and attempts to adjust the version number to make it work
properly.
Still will likely need some adjustment.
Created a test script to keep track of changes between versions. This
will help quickly identify if a change breaks a specific signature.
Version differences are stored, and the current version is checked
against a baseline and the previous run.
Will start including this in the pushes.

Results against baseline:
Files /home/vf_tests/1398778597 and /home/vf_tests/0_baseline are
identical
Results against last run:
Files /home/vf_tests/1398778597 and /home/vf_tests/1398778243 are
identical
