/**
* Display the admin/language menu and process strings translation.
*
* CHANGES
*
* 2006/06/08 mudrd8mz
* 1) Fixed bug 5745 reported by Harry Smith so now can edit en_utf8_local pack
* 2) More notification messages included
*
* 2006/05/30 mudrd8mz
* Merged with version by Mitsuhiro Yoshida - display icon links instead of text links
* (I have changed the position of arrow icons to not to be so close each other)
*
* 2006/05/19 mudrd8mz
* A lot of changes to support translation of *_utf8_local langugage packs. Needs testing
*
* 2006/05/16 mudrd8mz
* 1) LANG_DEFAULT_FILE can be now set. moodle.php used to be opened automatically.
* As it was (and still is) one of the biggest files it usually took a long time to load the page
* even if you just want to choose the file to translate.
* 2) added links from "missing" to "compare" mode page
* 3) english strings are now key-sorted in "missing" mode
* 4) list of files with missing strings is now displayed at the top of "missing" page
*
* 2006/05/14 mudrd8mz Improvements of lang.php,v 1.65 2006/04/10 22:15:57 stronk7 Exp
* 1) "go to first missing string" link can be displayed (see LANG_DISPLAY_MISSING_LINKS)
* 2) "go to next missing" link can be displayed (see LANG_DISPLAY_MISSING_LINKS)
* 3) submit button may be repeated (see LANG_SUBMIT_REPEAT*)
* 4) added (empty) "summary" attribute for the <table>'s
* 5) added error_reporting(E_ALL ^ E_NOTICE); in "compare" mode (even in debug environment
* we know that missing keys are missing strings here, not bugs ;-)
