Tag parsing issue

[HoreaM]

I noticed 2 small issues:

1. Basically, I generate the tags based on the folders where the models are. If I have a model in a folder for example called "TEST3D", I expect that tag created from it would be "test3d", but it is instead "test3 d" with the added space after the number.

2. Title of the model is generated based on the folder where the model is, but if the folder is named for example "TEST-3D", I expect the model would be called "TEST-3D", it is called "Test 3d" instead, with the uppercase characters converted to lower case and the dash replaced with a space.
