; Function Name: Load_BMP_From_Mem
; Description: Loads an image which is saved as a binary string and converts it to a bitmap or hbitmap
;
; Parameters: $bImage: the binary string which contains any valid image which is supported by GDI+
; Optional: $hHBITMAP: if false a bitmap will be created, if true a hbitmap will be created
;
; Remark: hbitmap format is used generally for GUI internal images, $bitmap is more a GDI+ image format

; Error codes: 1: $bImage is not a binary string

To do:Wenn man eine GUI erstellt, sie mit einem neue Icon versieht, die GUI löscht und eine neue GUI erstellt und sie wiederum mit einem Icon versehen will, funzt das Ganze nicht mehr! 
Sollte jetzt funzen.
Läuft nur unter x86 Mode!
