Servo Tuning wont open

Thank you very much!

Woow this is a very stupid mistake... in my .ini file i had an extra HALFILE called chaintoolchange.hal but it didnt look like this:

HALFILE = chaintoolchange.hal

instead it looked like this:

HALFILE =chaintoolchange.hal

i forgot to put a space between "=" and "c"...

i dont know what this has to do with the Tuning window but

now i dont have to close, correct, start linuxcnc and home the machine over and over again anymore

This is handled ok in the master branch (2.8~pre) so i've added a commit
backport a fix for the next 2.7 release.
