[CONFIGURATION] BUG: PKGBUILD: Add missing packages to makedepends

[munix9 <munix9@xxxxxxxxxxxxxx>]

One question in advance: Is there a particular reason why the 
functionalities of Github are not used in full? E.g. the 'Issues'?
On the subject of 'PKGBUILD':

For the build to work, the following packages *must* be removed from the 
'pkgname' variable:
'gambas3-dev' 'gambas3-devel' 'gambas3-gui'

I have no idea where they come from, but if they are removed, the build 
will work.
