catgod pretender viewer bug fix

[Evil Dave]

I've fixed the bug Arralen reported in catgod. It'll no longer crash if passed a non-Dominions3 file, but instead will return an error message and continue. Sorry, I still can't distinguish between Dom3 files (like .trn and ftherlnd), but so far, my testing shows that catgod merely generates funny results for them and goes on.

Download the new version of catgod for Windows, Mac OS, and Linux.

Yup, still command-line only... but Arralen is working on a GUI.

Once you've downloaded it, change to your pretender directory (usually dominions3/savedgames/newlords), and start looking at files.
catgod *.2h
will show them all.

Thanks to PvK for rebuilding catgod on Windows, and to Gandalf Parker for rebuilding it on Linux. (I usually build it on Linux myself, but I did something stupid to my Linux system... )
