Official Library File Format Restictions

I made the change to required all lower case. This involve removing the option for A-Z from the allowed characters and changing the note at the end of the paragraph. 

I also changed the extension portion and added a section about texture files.

Extension

All files in the LDraw Parts Library are required to carry the .DAT extension.

.DAT has to be substituted by .dat. Otherwise the whole discussion will start over again at the next revision.
