Added ability for MySQL tables to be created as InnoDB instead of MyISAM.
Users may now rename feeds.  Specific tags/feeds may now override the default item ordering.  Fixes to MySQL schema, and more.

MySQL schema was not creating foreign keys correctly.  TODO: migration.

Subscription preferences now hold alt_image and alt_title.  Titles and images now use these if available.  TODO: drop these from feed table.

Viewing a collection of items (a set of feeds and tags) now supports custom orderings.  Added fof_db_view_*() functions for manipulating these persistent view settings.  Added FOF_VIEW_TABLE and FOF_VIEW_STATE_TABLE.

Fixed issue where sidebar refresh would lose track of view details.

install.php now checks for existing 'admin' user_level instead of user_name.

Added feed-detail.php, which allows control of subscription settings, and viewing of more feed data.  Currently looks pretty janky.

Replaced occurrences of href=javascript: with onclick=. (Excepting bookmarklet link on add.php page.)

Moved db table name defines into fof-db.php, from fof-config.php (where they may still be overridden if need be).
Merge branch 'custom-views'
Fixed issues in recent MySQL changes.

View table constraint had extra =, item table foreign key lacked parens.  Padded empty IN clauses so MySQL parses them.
Also fixed typo in fof.js for order pref saving.
Fix prefs.php for custom feed titles.
