Enable the command line --debugflags before engine.init()
|Reported by:||jvprat||Owned by:||sev-|
As described in the wiki HOWTO-Engines, the engine specific debug levels should be added in the engine constructor. Then, one would expect to be able to use them in the init function, but they only work if you call enableSpecialDebugLevel and not when enabling them via the command line. The attached patch enables the command line debug flags before calling the init() function.
