Made scanning for mounted devices configurable (yet totally untested).
The default behaviour is to scan for mounted devices as before.
Let methodFinishFindDevices store true in result to indicate that the device search has finfished.
Merged branch with support to disable scan of mounted devices

Merge branch 'master' of https://github.com/LuHee/GarminPlugin
