Remove spaces from the version label in the panel UI

Before:

After:

Though, a better approach would be to use % formatting like so:

bl_label = "Molecular+     v%d.%d.%d" % (bl_info['version'][0], bl_info['version'][1], bl_info['version'][2])

Please let me know if you want me to do that instead.

If it works it works .. you decide

I think I'll use the % formatting as that's the "right" way to do it (plus it's more readable IMO).

go ahead will merge after that

Sorry for the delay.

I went with a slightly cleaner code that's already in use here.
