Patch allowing display table control characters

Hi,

I often need to show in table control characters | and ^. (E.g. ls | wc
-l, egrep -i '^expression' file).

As far as I know DokuWiki does not support using these characters in
tables. Therefore I write this patch. It simply adds pattern into
parser to allow using them together with '\' prefix.

Now I can type ls \| wc -l or egrep -i
'\^expression' file and I do not have problem with table.

I would appreciate your feedback.

 The toolbar now features three new buttons to insert a headline. Instead of
 asking the user for the headline level it asks if she wants a higher, lower
 or equally leveled section (relative to the current one).

 This means the user no longer has to count in which section she currently is
 and encourages users to use the proper order of headline levels.

 To make room in the toolbar, the old buttons have been moved in a picker.
