the new template allows to use a favicon in media/wiki/favicon.ico so we
should support uploading it as well.

This also fixes a problem wiht PHP 5.4 when there is metadata but the
date key is empty.

Fixes messages.txt's modification timestamp not being updated.

This bug occurs on systems where writing a zero-length string to an
empty file does not update the file's modification timestamp.

This leads to the messages.txt being downloaded almost endlessly, causing
long delays for logged-in users. Visitors are not affected, because the
messages.txt is only updated for logged-in users.

When a plugin file exists, we can assume it is the correct file and load
it without error supression. This makes it much easier to detect and
debug problematic plugins.

In some circumstances the username was set in latin1.

This prevents an "Illegal string offset" error in PHP 5.4 in the test
cases (the integration tests failed here with PHP 5.4).

Call-time pass-by-reference is a fatal syntax error in PHP 5.4 and
stdClass objects can't be instantiated automatically anymore.

Previously when in an event handler the same event was triggered again,
only the handlers for the second event invocation were all executed, the
handling of the "outer" event stopped after the handling of the inner
event as they both used the same iterator of the hooks array. This
caused caching bugs e.g. when both the include and the indexmenu plugin
were enabled as both of them load metadata in the cache handler which
triggers another renderer cache event.

This allows easier identifying of which version has been restored (FS#2522)

some tweaks to the pagetool css FS#2481

Changed style of notification messages

for info on them.

This was fixed in upstream and the upstream tests caught this :-)

seems like phpunit will not run all test classes inside a file when
giving it as an argument :-/

I removed the error supression tests as these test a feature we do not
have in our JSON class version (and shouldn't implement to keep as
compatible as possible to the native JSON functions)

upstream plus a test for our modifications

Replace SimpleTest with PHPUnit

Input iteration counts are squared in the function and passing something
above 30 is giving integer overflows on 32 bit systems (and causes insane
iteration counts on 64bit systems).
