adds remaining functionality to ignoring ETag, fixes issue #50
Merge branch 'force_reload' of https://github.com/ljleppan/festapp-android into force_reload
General structure for forced data reload. Does not work _yet_.
Fixed forced data reload.
Fixed ignore etag checkbox.
Merged upstream changes.
Resolves partly issue #43.

Stages are no more hardcoded. There is default json file,
which is parsed to the database. The database is updated
periodically (like other tables) from the server side.
Removed redundant StageType.
Removed unused import
Oops.. almost saved wrong Stage values to db.
Removed unused code and mappings. Basically nuked some of last nights wtf-solutions and left only what was really needed
Removed wrong log message.
Fixed the location of semaphore release.
Fixed comments given to PR.
Removed etag ignore checkbox alltogether. Fixed the force load so that it also ignores the counter and date checks.
Moved the debug flags to FestAppConstants.java.
Change getOnly* methods to getOnlyLocation().get*()
Remove commented out code in FestAppMainActivity.java
Merge branch 'master' of https://github.com/futurice/festapp-android into force_reload
Fixed StageDAO server queries to really work.
