Updating generate directory README removing information about old scripts and adding mention of the new Devel Generate module

removing generate-content.php, generate-taxonomy.php, and generate-users.php - now replaced with the devel_generate.module

#130989 - Devel Generate module - autopopulates the current site with users, taxonomy, and nodes - replaces the old generate scripts with permissioned and configurable administration pages

rollback of ltr patch. i am not seeing devel output render on page properly with this. the section is empty

move lots of devel_exit() stuff like query log and memory log to a shutdown function. we now get more accurate memory usage and more importantly, the 2 write queries in sess_write() at the end of every request are now shown. lets get rid of one or both of these through refactoring of throttle and who's online features.

automatically show large data structures within a textarea during dprint_r(). early code by irakli. modified by moshe weitzman ... minor function rename too

remove automatic block enable feature. it didn't work 100%, and some folks dislike the php block in particular

show sumamry query information even when query log is disabled and timer enabled. also change a bunch of strtr to t() since we rejiggered bootstrapo so that t() is legal in hook_init and hook_exit()

the variable viewer is replaced by a fine variable editor. patch by moshe weitzman ... i would be pleased if someone figured out how to add the fancy checkbox range behavior to this form.
