Changes to NG911_DataCheck, NG911_Frontend

Made changes that should allow the first data check, Check Layer List,
to be ran from within the GUI.
Ignore .pyc and archive version of NG911_Frontend.

Keeps git from trying to always upload the .pyc files. Also keeps it
from trying to upload an older version of the NG911_Frontend that I keep
around incase I forget how I did something previously.
Merged conflicts in 2 files.
Comment updates to NG911_Frontend

Changed a few comments in NG911_Frontend.py to better indicate
development progress.
Merge pull request #7 from dirktall04/master
