Small mistake in the regexp for validate_alpha_dash and validate_valid_name

[ben-s]

Hi,
In the corrections you made yesterday, I can see a small mistake in the regexp for both methods validate_valid_name and validate_alpha :
if(!preg_match("/^([-a-z0-9ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðòóôõöùúûüýÿ_-])+$/i", $input[$field]) !== FALSE)

As you can see, the first dash is unseless since it is given at the end of the regexp.

Thanks for picking that up, Ben.

I've fixed it in: http://github.com/Wixel/GUMP/commit/67f1120cce361e113cc0cdd005cb1d36dbf64c00
