gtspam 5.x-0.3

The purpose of this module is to achieve the same behaviour as clicking an usual mailto: link, while obfuscating email addresses to help prevent spambots from collecting them.

This release focuses on producing output that is W3C XHTML 1.0 compliant, as proposed by marvil07 in issue 169556.
The changes were:

1. removed the <nobr> tag (why the hell did i use that tag?!) and now use the more compliant CSS property white-space with value nowrap to achieve the same result.
2. changed the <iframe> for an object tag, to be compliant with the XHTML-Strict mode.

However, there's still one thing in the module that produces output that is not XHTML-Strict compliant: the anchor target attribute, but i can't just cut it off. So, for now, this module can only be XHTML 1.0 Transional compliant.
