Recursive Tag parsing sometimes triggers table-code where it should not (was: W2L throws a Notice in Table-code)

[GoogleCodeExporter]

Using this footnote causes an php-notice:

<ref>!!!</ref>

Parsing this footnote triggers some table-code, which then throws the notice:

Notice: Undefined offset: 0 in
/var/web/studium/extensions/w2l/w2lParser.php on line 1497

I corrected this problem. It might occur in other instances, so I leave it open 
for now.

Now table code is only triggered, when there really is a table in the string. 
Still no perfect solution, though :(

This big is also triggered by a simple line containing plain "!!!"

Added a check, if we are in a table at all. This fixes the problem in a small 
test I created. Hope it works in other instances, too.
