[Therion] cannot load thconfig in xtherion

[Wookey]

If you run xtherion then try to load a thconfig file you get this error:

<path>/thconfig.thcfg does not exist

It works if you run

xtherion thconfig

(or otherwise specifying the correct path to the thconfig file)

So something in the codebase seems to have decided that thconfig files 
must now be called thconfig.thcfg or thconfig.thconfig. This seems quite 
broken.
