z-index handle changed.  every value used only once from 1 to n.
Fix most of InflateParams, ignore others
Fix GradleOverrides
refactor Lint options

- only specific Lint ignores reside in lint.xml
- remove unused res-folders
- ignore unused drone.png file - code currently commented
- some code formatting (auto formatter)
fix inflater issues

all fragments which are inflated using FragmentManager,
need to use the three parameter inflate method with attachToRoot
set to false; otherwise the app crashes with following error message:
"The specified child already has a parent".
Three parameter call of inflate is also used for adapters - see
http://www.doubleencore.com/2013/05/layout-inflation-as-intended/.
using the inflate method without setting attachToRoot caused
"java.lang.UnsupportedOperationException: addView(View, LayoutParams)
is not supported in AdapterView"
update gradle check task

- move checkstyle and lint config files to new config folder
- remove .checkstyle files, which are only needed for Eclipse
- output folder for lint and checkstyle results set to build/reports
- activate pmd 5.1.1 (gradle 1.12 default is 4.3)
- toolVersion property is deprecated - but haven't found a workaround
- rulesets with excluded rules are moved to specific
ruleset files containing only one ruleset.
one general ruleset file did not work - excluded rules were ignored.
see http://stackoverflow.com/a/23546851/2093483
- gradle check task now executes pmd as well
update gradle build file

- update to gradle build 0.12 (needed for android studio 0.8+)
- rename android plugin (there is a lint check for this)
- ignore new warnings; should be fixed in the future - left a comment

quickfix for uitests

- no context available; currently hardcoded program names
  needed for cleaning up pocket code directory
- BroadcastBricksTest caused IndexOutOfBoundsExceptions -
  starting from MainMenuActivity should work
- modified SettingsActivityTest; testOrientation tested
  MainMenuActivty instead of SettingsActivity
- WebView methods have to be run on the UI Thread -
  at least our new emulator (api18) complained
- move randomly failing testcases to Devicetest
- delete SharedPreferences projectname - could cause
  Nullpointers on later tests
