Issue #5 Fixes crashes when rotating the app

Removes the constructors and use Bundle to pass objects to the fragments.
Also includes the quick-and-dirty-way to keep the state while rotating the app.
Issue #5 Fixes a few more crashes when the app is exited and reloaded after beeing OOM-killed.
Moved the FragmentSwitcher to a static service instead of passing around an instance to fragments.
Issue #5 A few more serializable crashes fixed for Episodeplayer.
Moved the episoderplayer to a static service like Fragmentswitcher to avoid having to serialize and passing things around in the Bundle.
Removed a bunch of unused imports and old EpisodePlayer references from MainActivity
Live episode archive added.
Added Feedburnerparser to parse the episode archive (to be replaced with own webservice when it's done).
Parse episode archive trough an asynctask.
Temporary removed the holder pattern from the Adapters since it caused caching problems and playing the wrong episodes (need to look into how data model assignments to rows actually should be done).
Set the clicklistener on new and found rows. Now the correct episode is playing when selected.
Removed debug println.
Display progressbar when an episode is selected and until player starts.
Shows episode duration and date in episode list
Some smaller layout/fragment changes to include a player at the bottom
Added interface between play/pause-button and seekbar.
Updates the status on the buttons and allows the user to seek in the currently playing episode.
Doesn't work 100% when the application is quitted (but still playing in the background) and restarted yet.
Basic MOVEON!-button with timeout to prevent spam  (currently it needs to restore the timer since it's lost when switching fragments.
Serialize the episodes between sessions to avoid reparse the whole RSS feed everytime.

Stop the rss feed parsing when an existing episode is found in the set.
TODO: add reload functionallity (button or PullToReload)
Show overlay with position when seeking in the player.
Reconnect the player interface with the player service when the application is relaunched. (If it's been OOM killed for example).
Restore play/pause button state on reconnection.
Display how much time that has been played of an episode.
When an episode has stopped playing continue to the next. (Might need to be moved to Episodeplayer instead because it might not work in the background now)
Don't update the seekbar with progress when user is seeking.
Don't try update progress when player is paused.
Instead of play an episode show a page with the itunes:subtitle and a play/view button. Later on view will play the youtube video.
Animate pages going to the backstack with a right_in and left_out animation. (A bug exists in the popexit where it shows the new fragment directly).
Solves the transtion issue with a correct overlay during animation leaving the old fragment in the background.
Hide player buttons and seekbar when displaying the live view.
Fixes the problem with transparent live fragment showing parts of the previous fragment.
