Renamed Mercurial class to MercurialBridge
Bumped dependency to 1.47-SNAPSHOT and implemented MercurialComparator
Fixed assertion error
The compare method in the comparator is now actually invoked
Comparator now seems to work with the default branch
hg calls now uses the correct workspace
Constrained MercurialComparator to only run when actually activated
Refactored SCMInterface to SCMBridge in the entire project
