#143249 by Jose A Reyero: add language parameter to t() to make it possible to retrieve translations of strings for different languages, to send emails to users in their own language for example

#136837 by meba: PHP replaces {} enclosed variables in strings with the variable value itself, so cache tables were not prefixable

- Modified patch #142798 by Steven and sime: introduced a new image API function: image_scale_and_crop()

- Patch #99011 by merlinofchaos: remove sites/default/settings.php and ship with sites/default/default.settings.php.

- Patch #137211 by merlinofchaos: move theme information to .info files and improved theme inheritance.

#141482 by Heine: collapse custom language addition form by default, because it is an advanced form, not required most of the time, so can make people confused

#127539: progressive operation support, refactoring update.php code to a generic batch API to support runnning operations in multiple HTTP requests
  - update.php is already on the batch API
  - node access rebuilding is in the works
  - automatic locale importing is in the works

 Thanks to Yves Chedemois (yched) for the good code quality, very wide awareness of issues related to batches,
 and the fantastic turnaround times. Hats off.

- Patch #67893 by kbahey, dww, alienbrain, asimmonds et al: made it possible to filter log messages in the database log.

- Patch #137415 by slantview: simplified the cache API/usages, and made it a tad smarter.  Makes it easier to program for, and easier to replace.  Will need to be documented.

 - typo fix in watchdog() phpdoc
 - add a missing array() on a watchdog call in ping.module
 - handle NULL 'variables' value in syslog module

Noticed these while writing the documentation for watchdog() updates and by comitting the updates into the i18n SVN repository.

- Patch #138376 by dww: fixed array vs. string bug when defining #default_value array for a multiselect.

Leftover variable name spotted by Amr Mostafa, reported by email (because 'the fix is too small and trivial to submit an issue')
