Add more proper input handling

Certain injection attacks could work on the title section. Overall it's
"safe enough". Sanitize function phased out.
Add admin controls, post edit/delete, blog comments.

Wysiwyg editor now modularized, add/edit works properly, delete works,
admin options visible if logged in. Can log out. more template modularizing.

Using master-comments-system. Needs to be integrated with css still.

Needs pagination.
Match master-comment-system display to template.

Still in progress.
Fix issues in comments.class.php. Comment types make more sense.
Fix anchor bug in comments.

Added jQuery scroll replacement for the anchor method. Not beautiful, but
more compatible. Required changes to the class file.
