gladevcp - iconview.py - bug filling store if filename has several dots

files containing two dots in there name was not shown in iconview.
i.e. Pocket 2.5 step(1).ngc has not been shown, now only the most right
dot is used to get the file extension

corrected that
gmoccapy_postgui.hal - wrong "=" sign caused error on start up
Merge branch '2.6'
