First draft with fixed Option-Switching

I fixed a Bug in this Version:
-> Options can only switched 1 time after Program-Start

I added in this Version:
-> Check if RPG-Maker Directory is valid
-> Enabled the option to dis/enable the RPG-Maker dir validation

I also included the About-Window... Its not so important but its done now.
I had also included many Libs that I will use in further Versions so yeah its a little step forward

Please Download this Version, because that Bug with the Options is really bad >.<
