improper handling of [[:Image:____]] in version 2.5 SVN for MediaWiki

[pkoppstein]

For example:

[[:Image:X.jpg|image page]]

becomes

[[Image:X.jpg|image page]]

I've marked this as "high priority" because the image itself is embedded on the page, instead of a hyperlink to the image description page.

The problem has existed for some time and can be seen for example in version 2.5 SVN build 19965.

Fixed with [2388] (massive commit, it's a trick with "RTECOLON" string).
