Implemented a basic commit msg listview
Added Encrypter class
Merge branches 'gitrepocommits' and 'master' of https://github.com/Sajfer/EDA397-Group6
Integrated my stuff and Johan's stuff with the latest master branch, + made some small fixes. Major overhaul to sharedpreferences so delete any old data from the app (removed everything to do with current/currEdit, since we always want to check if the account is still valid/if the GitFunctionality singleton is still alive). Switching between viewing repos/commits on repo works perfectly.

New stuff I have added is mainly encryption + adding back the code to retrieve related organization repos as well.

BUGS:
No way to log out (except back button). Pressing hardware menu button crashes the app (previously it would activate the menu button on the activity bar).

Some parts of Johan's code is commented out, affecting logged messages/ text shown in repo commits list. Basically any calls to RepoCommit.getCommiter crashes with a nullpointer, but getCommit works.
-Removed unused imports
-Changed hardcoded strings
-Removed getRepos from the onClick in mainActivity
Disabled menubutton (and back button in login). Removed watch? checkbox. Added some stuff around the getorganization repos code, which should hopefully  stop it from crashing on users that don't have orgs.
Merge.
Merge.
Added more info on repo commits.
-Removed unused imports
-Added comments to new functions in GitFunctionality
Update README.md
Added tab layout. Some functionality might be deactivated.
Repos and commit stuff now works with tab interface.
Working code for retrieving file names (extremely slow, may crash on larger repos).
Separated getting filenames into its own method. Works but is slow, would be fast if we decide to only get files for 1 commit (basically only show files when a commit is selected).
Separated commits into two parts for better performance (need to be able to go back as well?)
added private class for getting all the branches for the repository
added function that returns the list of the branches
Merge remote-tracking branch 'remotes/origin/master' into GitBranch
Added one more tab for branches successfully and printing out number of branches
