gimp2: configure fails without python support

[ryandesign (Ryan Carsten Schmidt)]

Trying to install gimp2 without python support fails:

$ sudo port -d install gimp2 -python27

configure: error: 
*** Could not find PyGTK 2.10.4 or newer.
*** Please install it, or skip building the python scripting extension by
*** passing --disable-python to configure (but then you will not be able
*** to use scripts for GIMP that are written in Python).

There used to be a no_python variant which added --disable-python. It was removed in r115501, and that was the right thing to do, but the --disable-python argument needs to find its way back into the configure.args if none of the pythonXY variants have been selected.

r115553. Caused by late night typing accompanied by sleep. Thanks.
