refactor page saving and introduce COMMON_WIKIPAGE_SAVE

this was an accidental commit to master

This reverts commit f7f7fb6c.

This introduces a mechanism to override what happens when a media item
is selected in the media manager popup by providing a callback name in
the URL. The default implementation just does what
dw_mediamanager.insert did before and calls insertTags()

As discussed in #1471, an uninitialized variable will always be
implicitly created when passed to the blank() function. Calling isset()
is thus a no-op. A warning about this behavior has been added to the
function comment.

Adapt .htaccess files for Apache 2.4

This makes the saveWikiText() function a little easier to read and moves
external edit handling to its own function. Behavior stays the same
(tests are unchanged).

In addition a new event COMMON_WIKIPAGE_SAVE is introduced that makes
intercepting and acting on page saves much easier than possible before.

Developers can:

* prevent saves by either preventing the default action or overwriting
  the contentChanged field in a BEFORE hook
* enforce saves even when no content changed by overwriting the
  contentChanged field in a BEFORE hook
* Adjust the saved content by modifying the newContent field in a BEFORE
  hook
* Adjust the stored change log information (summary, type, extras) in an
  AFTER hook
* Easily know if a page was deleted, created or edited by inspecting the
  changeType field
* what ever they want before or after a wiki page is saved
