#3 fix memoryleaks in main application

[Mp3Freak]

there are still memoryleaks in main application.

reportmemoryleaksonshutdown:= true reports them but don't tell anything useable for fixing it.

There are two common options for finding them:
option 1) FastMM4 (Fulldebugmode) shows a lot of information, callStack, Position of leaked Object
option 2) Eurekalog (Demo) shows a lot of information, callStack, Position of leaked Object,
but I think a bit better than FASTMM, I think this is the best tool for finding memoryleaks.
Finding memoryleaks is not limited in Demo.
