#189878 by O Govinda, keith.smith: comment module help updates, removing help on features which are not there, and adding help on Drupal 6's new per content type comment settings

#199336 by JirkaRybka: remove improper t() use in update code (update goes all in English, but there were some mistakes), and add messages to updates where there was no return value otherwise, so users know what happens in each update

- Patch #164532 by catch, pwolanin, David Strauss, et al.: improve table indicies for common queries.

#194310 follow up by chx and myself: only load comment module when we can actually do it, and when we need it in comment.install

#194310 by chx, catch, KarenS: run updates for disabled but previously installed modules, if they are compatible with the current system

#197314 by vitezslav.smid (as GHOP 39): improve/add/update phpdoc in aggregator, comment and system modules

#200069 by keith.smith: new standard for 'more information' links in module help texts, as the handbook we referred to before was renamed

#197297 by DanW (as GHOP 17), and keith.smith: clean up lots of help texts, update to drag and drop functionality, drupal.module removal, etc

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

#195678 by catch: standardise on Save and Preview button terminology (for comments) and button placement for comments and nodes, so Save is always the leftmost button, and there is no guessing to find it

#191104 by keith.smith: (usability) change occurances of node to 'post' and 'content' as appropriate

#189837 by chx: remove temporary table usage from comment_enable(). Now we require MySQL 4.1 and it has constructs which make this unnecessary.

#186749 by Rob Loach and myself: (regression) only override comment submitter name with anonymous name, if it was not provided already

#187391 by jrbeeman, catch: redirect user to proper node comment page after submitting a new comment

#93425 by bjaspan: remove pre-Drupal 4.6 era destination handling cruft carried over in comment module

#177497 by chx and Desbeers: revive Drupal 5's menu_set_location() functionality by introducing menu_set_item() (for consistency in function naming), thus fixing a regression in the current development code. Also fixing some misuse of menu_set_location() by using drupal_set_breadcrumb() instead.

#184867 by deekayen, catch and keith.smith: fix some spelling errors in our source code and messages printed

#55277 by catch and JirkaRybka: when flat comment view is used, order comments by cid (ie. original submission order) instead of timestamp (ie. last editing time order) to avoid comments jumping around when being edited

#183390 by hunmonk: forms should use form_state['redirect'] for redirection, not drupal_goto() - fix this in comment_admin_overview_submit()

#181088 by fajerstarter, catch and JirkaRybka: rename 'access control' to 'permissions' for usability reasons

- Patch #180432 by hunmonk, sun, et al: make comment settings per node type.  This is a new feature that slipped in because it is required for the project module on drupal.org.

- Patch #150245 by webchick, bjaspan, ralf, Arancaytar et al: move the .schema files into .install files to prevent mistakes.

#180559 by hunmonk: do not try to display the comment addition form at th end of comments, if we are already on the page, so it is displayed anyway

#177927 by chx: use path=/ in PHP comment settings cookie creation, so cookies set around the site are available in other 'directories'
