release 0.5.1

[filippo]

Hi all,
I've added a new release that can be downloaded here:
http://code.google.com/p/sgte/downloads/list

Changes:
- attribute names now must start with characters a-zA-Z_
this avoid collision with javascript libraries such as prototype or
jQuery where you can have $('someID') as an alias for
document.getElementById('someID'). This change has been in the trunk
for some time.
- added .pub file for CEAN
- internationalization improvement:
added sgte:gettext_init function. It scans sgte source files for
gettext strings and creates the .po template file.

Cheers,
filippo
