cecho improvements for links

[Vadi]

Would anyone mind improving cecho to work with embedding links as well? Right now, if you want to include clickables, you have to go the extended manual way of several function calls per echo :-/

I added cechoLink, dechoLink and hechoLink. When I get around to fixing cinsertText, I'll add cinsertLink as well.

Aha. Thanks a ton, I'll check it out later today.
