• Update

I asked in the thread of the Wesnoth forum, that appears in the wml.xml file (http://www.wesnoth.org/forum/viewtopic.php?f=21&t=13781), if the changes are OK and someone has suggested to me that the array indices (array[0]) aren't highlighted as tags, as well that I included it

Changes:

• kateversion to 5.0
• Delete commented code
• Don't highlight tags if there is an alphanumeric character, underscore or "]" before, to avoid highlighting array indices as tags.
