This will be fix for Gambas 3. 

I won't fix it for Gambas 2.4, as you will be able to make 2.4 projects that 
cannot be compiled on 2.3 then. Maybe this is not a good idea!

But it is just a compiler limitation, it won't change anything in the 
bytecode. Internally, "PropertyName = xxx" will be compiled the same way 
as "ME.PropertyName = xxx".
