#461938 by grendzy, JamesAn: Use filter_xss_admin() on site name and site slogan, just like footer message and mission

#465190 by Heine: The Anonymous name is a plain text setting, so it should be escaped properly for output.

#220559 by eMPee584, Desbeers, Damien Tournoud: only ever add the active class to links in l() and theme_links(), if the language was set and is the current language or if the language was not set on the link

#333060 by neclimdul, merlinofchaos, dvessel: child themes did not inherit patterns correctly, so more specific template files are not detected

#258089 by JohnAlbin, Arancaytar, merlinofchaos: themes cannot have a preprocess function without a corresponding .tpl.php file

#297952 by aaron, merlinofchaos, dvessel: Reserve the 'template_file' variable instead of the too generic 'file' for template file inclusion. This makes 'file' available for themes.

- Patch #252430 by quicksketch: allow base theme prefix in preprocessor function names to correct expected behavior.

#197124: even though documented and intended, themes could not remove module stylesheets by specifying their name with a non-existent file

#266367 by zeta z: improve code documentation on how modules should provide default theme hook implementation

#241570 follow up by merlinofchaos: the previous patch was inverting the problem with theme preprocess functions

#258120 report by dag, patch my myself: l() attributes were not updated properly to Drupal 6 in theme_username()

#241570 by merlinofchaos: original hook name was not carried over when using patterns, so preprocess function collection was broken in that case

#172571 by fgm, slightly modified: document that theme_xml_icon() was superceded in most cases by theme_feed_icon()

#208768 by dvessel, Arancaytar: language direction should be in the HTML source, so it is more accessible even without CSS

#210479 by catch, dvessel: add newlines to list items, so inline display and RTL issues are resolved

#208991 by JirkaRybka: target sticky table headers to Drupal output tables only, so it won't sticky random tables in other site content

- Patch #204900 by webernet: code style fixes.  Likely my last patch of the year.  Fiew.  Thanks all, and see you on the other side.  :)

#201536 by chx: centralizing permission checking code in node revision handling, removing lots of duplicate code

 - possible timeouts with installing/enabling lots of modules at once in core
 - enable install profiles to have more modules without fear of timeouts on install
 - bootstrap Drupal before each module load, so previously enabled modules are bootstrapped
 - let modules run their hook_requirements() (although actually calling them will be possibly fixed in another patch)

 - whitespaces at end of lines
 - indentation
 - control structure usage
 - whitespace in empty lines
 - phpdoc comment formatting
