one thing of my list, this one had to wait a long time......

- fix cut and paste error of comment in the oem-recovery-part-size element
  definition
  + comment is displayed in the generated doc and was misleading
- add unit test for {g,s}etAtaRaidScan method on OEMConfig class
- add unit test for {g,s}setRecoveryPartSize method on OEMConfig class
- fix bug regarding oem_recoveryPartSize
  + the value was never set as member variable thus the get method
    always returned <undef>
- fix naming inconsistency between the get and set method for the
  recovery partition size
- add value check for the recovery partition ID
  + must be a 2 digit hex value
  + also add unit test for this verification
