javascript for code highiliting, v0.3

Placed v.0.3 version.
It is more pretty.

Moved "<>" in the begining of keywords processing loop (by definition in basic.js).

Joined keywords by "|" symbol in basic.js to use as single expression without looping.

Further could be done improvements of comments, they are not working well in the version.
basic.js renamed to basic.js.txt, because it tried to be loaded from iframe.

Bothering alerts also removed.
