[TYPO3] Helping fixing some bugs in TinyMCE

[Tapio Markula]

Hi

TinyMCE looks really nice but it has some bad bugs
in typo3link plugin. Thomas has not have time to fix
those bugs.
Could Peter and other Typo3-specialist look at that
plugin and help fixing bugs. All of them relate with
redefing of existing links. That works *only* for
internal links, which don't have anchors.

It is a little bit annoying to tell customers that
they would not try to redefine existing links but just unlink existing 
links and totally redefine them.
