2 tests fixed
added Arduino_Send_Brick into the Master branch
ToDo: Functionality + Arduino Function Implementation
Inserted all Function Methods + Fixed all Bugs
Compiles on my Smartphone now without errors + Nullpointer Exceptions
ToDo: Test with Arduino BT Board
added detection for Arduino Functions in all bricks which contain a formula
added Arduino Support in the PreStageActivity.java class
Fixed crash bug when bt-connection timed out
Small bugfix, *crashes when trying connect*
refactoring to new bluetooth stuff
added some missing code
ToDo: Bt Socket is "connected", but nothing is transmitted (see debug output BluetoothConnection)
SendAction is not called from the ArduinoSendBrick (added debug statement)
changed prestage, devicelistactivity, bluetooth connection
rebased branch on the actual master + fixed all bugs (Brick + Functions are running as usual again)
added my old ArduinoSendBrickTests
extended my basic tests
1. create project with Arduino Brick
2. set LED pin to high
3. set LED pin to low

important: Bluetooth must be enabled before the tests are started
added some tests for Arduino functions
added catroidSourceTest.iml
