Mostly changes to rating bars
* more exact rating display (50 steps instead of 5)
+ new graphics for rating (also includes a green rating bar)
+ rating bars reset to 0 when hitting the rate button
* a few layout changes
* fixed a bug where rating a side dish would change the label of the main
  rating button
Threaded loading of data
+ App now loads data without locking up, instead displays a loading dialog and
  loads the Sigfood API in a seperate thread
+ Pictures are loaded after data has been processed, so pictures load in the
  background while the user can already read ratings and comments
New layout, splitting up Activity
+ New layout, using ActionBarSherlock to keep compatibility with Android
  before 3.0. This library is not included in this. Layout has been tested on
  Samsung Galaxy S+ 4.2.2 Cyanogenmod, Samsung Galaxy S2 2.3.3 Stock, Asus
  Nexus 7 4.3 ParanoidAndroid
+ Split up SherlockActivity into the Fragments MenuFragment, MealFragment and
  CommentFragment
* A bunch of fixes, chagnes and additions I did while I was already
  restructuring everything
o TODO: ImageButton mealPicture is hidden on MealFragment if there is no
  picture available - which means it's impossible to press it in order
  to upload one.
o TODO: Different layouts depending on screen size, to fit it better on
  landscape views or tablet screens
Splitting layouts
+ Split parts of layouts into fragments, so it's easier to make screen size
  or orientation specific layouts
* Fixed missing upload button on meal detail pages, when no photo is available
UI changes for bigger screens
+ UI now changes for bigger screens:
    + MenuFragment shows mainmeal panels in up to 3 columns
    + MealFragment and CommentFragment are split into two columns
* Changed the target to API Level 14 (Android 4.0). Still runs on 2.2+ though
* Fixed margin around comment boxes
