Big Changes!

Changed the Config file into 2 seperate files. FormConf.ps1 &
PSSConfig.ps1

The treeview section, is now able to make a pop-up gui. A function was
created to handle this.

Confirm-Config was created to make sure that the PSSConfig.ps1 file is
there. The FormConf.ps1 cannot be confirmed, as it contains things that
doesn't change dynamically. images etc.

Imagelist has been created for images, on then tabcontrols.

Review the code for the rest. A LOT has been added.
