- Patch #15962 by Goba: no need to drop the accesslog table to add a new primary key.

- Patch #15957 by Goba: reintroduce translateable watchdog types.

- Patch #15976 by Neil: if one single admin modifiable menu item is added then it is not put in the menu table because the comparison is > 1 instead of > 0.

   + The "add new comment" was missing for polls.

   + Renames $main to $teaser where appropriate to follow latest Drupal conventions.

- Patch #15978 by Drumm: code improvement: theme_forum_display() has no business calling theme_page(). Lets have it return the output and then forum_page() can put it in a page.

- Patch #15843 by Ber: in book-pages node forms we use a delta of fifteen (-15 to +15) but in the book-outline admin we dont dewfine this, resulting in a default delta of ten. This should be consistent and thus both 15.

- Patch #15847 by James: added rel="nofollow" support.  This is implemented as a filter so it can be enabled/disabled on a per-role basis (eg. some people might want to enable this for anonymous users but not for authenticated users).

- Patch #6847 by Gerhard: replaced vocabulary->nodes by a separate table and tidied up the taxonomy API a bit.  This fixes a number of issues.

- Fix tracker pager count query being wrong (it did not return a count but a set, and it counted nodes with more than 1 comment as multiple nodes).
- Clean up various SQL queries: removing literally inserted data (db_escape_string is evil!), fixing single "%" which should be "%%", fixing integers being compared as strings.

- Tiny code style fix

(e.g. admin.module was removed -> needs menu cache update).

- Patch #14731 by chx: made it possible to rewrite node queries.

- Patch #15570 by Drumm: integrated the admin and system module.  Renamed the callback as per Goba's suggestion.

- Patch #15337 by Gerhard: fixed bug in upgrade path.  The 'update_start' variable got corrupted.

Making the installation instructions a bit clearer for newbies and it explicitly explains that the commands are for the command line.

- Fixing broken "pagerank" detection
