Removed stray debug message in installer

Well I'm an idiot - the fulltext index on page_text was missing from a default installation. It didn't break searches but probably slowed them down tremendously. Also set engine to MyISAM on page_text to avoid cryptic error messages from MySQL.

Major improvements in the security of the CAPTCHA system (no SQL injection or anything like that); fixed denied form submission due to _af_acting on form object wrongly switched to true

Javascript validation for install DB info form didn't allow dashes

Changed default content for the main page to something a lot more user-friendly and helpful

Rewrote some security code in PageUtils::savepage to accommodate the ACL system better; there was an issue with non-admin users saving pages on which they have edit rights but wiki mode is turned off

Fixed: secure-cookie option is no longer set if $_SERVER['HTTPS'] is set but == "off"

Patched in dash-in-database-name fix from unstable

Merge in installer fixes from 204 (ba28d43a6b86)

Merging in all changes from revision 185 (90b7a52bea45)

Fixed a few (more) MySQL issues with the installer and dashes in the database name

Database name can now contain dashes (as per requested at http://forum.enanocms.org/viewtopic.php?f=5&t=14); corrected some installer behavior issues with connecting as root and setting up permissions resulting in logs not being flushed, configs not being inserted, and what have you.

Cleaned up some HTML in the installer; corrected some phpDoc syntax errors

Fix installation with MySQL root option

Out with the old, in with the new. Welcome to Enano's new installer framework!
