Changed the keywords again.

This time, I also changed the Kate editor xml file.

This commit sets 32 keywords for LFyre. There are a couple of notes to
be made:

* First, even though templates were added back in, the template keyword
    was not. That is because the compiler and programmer should recog-
    nize templates when they see them.

* Second, 'func' and 'tuple' were taken out, mostly because they fit
    predeclared types better.

* Third, 'fire', 'go', 'fall', and 'assert' were added.

This commit does not change the lexer. That will be done in the next
commit.
