Add parser for boost logging

[miklelappo]

Allow projects using boost logging to use nice rogcat colours

The setup for boost logging should look like this: "%TimeStamp% %ProcessID% %ThreadID% %Process%: %Message%"

Closes #36

Is there somewhere a definition of the "boot format"?

[miklelappo]

Boost logging is setup via logging.ini file and can take many different forms. The proposed format is as close as possible to android one which is the best from my ppov.

Format= "%TimeStamp% %ProcessID% %ThreadID% %Process%: %Message%"

Puh. This requires very detailed knowledge in order to get setup. My feeling for the future is more to get rid of formats and focus on the formats used by logcat. Started this with https://github.com/flxo/rogcat/commit/281dc3ab633536cc8d3d99d16861c27cc799e5f1.
