Minor change to classTextile

[tommyyoo]

Hopefully nothing major:

• remove the use of the split function (deprecated in PHP 5.3)
• addition of emspace and enspace
• use of two spaces in a row to enter emspace

[textpattern]

Textile was recently moved out of textpattern so it could be developed independently.

The current location of the PHP implementation is over with Netcarver.

I believe he is working towards allowing Textile to be expanded via textplugs - which should allow you to extend the glyphs. This commit fixed the deprecated split, iirc.

Understood, thanks!
