Additionally, *cough* *cough*:
* Add a Title::isMainPage helper for the fairly common $title->equals( Title::newMainPage() ); test.
* Update wfMessageFallback to also accept an array of message keys instead of requiring them listed as arguments to the function.
* Move the bulk of wfMessageFallback code into Message.php instead of leaving it in GlobalFunctions.php
* Change the wfMessageFallback implementation so that the Message class handles the fallbacks themselves eliminating any side effects caused by the fact that wfEmptyMsg always used usedb=false, language=userlang when one might actually use a different language or usedb setting in the message object that actually returned the text (this may be considered a wfEmptyMsg regression in 1.18).
* Make blank "" message contents fallback like nonexistant messages do.
* Re use the new tabAction array handling used to support mainpage-nstab in the talk and view tabs instead of making wfEmptyMsg calls directly in SkinTemplate.
* Don't call params() for every param passed to the constructor
* Use self
* Use array_merge() instead of += , the latter behaves contrary to the documentation
* Fix capitalization of toString() calls
* Various style, typo fixes
Options is now to value members: format and useDatabase.
fetchMessage() can be overwritten to use other message source
like for example testing purposes.
* Just one function for adding parameters, not three.
* Implement an options framework: one extra widget (get-message-not-from-db) already in use in wfMsgNoDB(), others will probably follow, so set up something to keep them clean.
* Lay the groundwork for supporting __tostring() when MW stops supporting PHP < 5.2.0
* Fix various fatal and non-fatal errors
* Make use of r64178 to clean out any dependency on the wfMsg* functions.
