Fix #852, $_table renamed to $table_name

Apparently when changing the $_table var to $table_name I was not
thorough enough, and when addressing #843 I was still not thorough
enough. In this case I searched the codebase for $_table and
$this->_table and ::_table. The migrations likely did not need the
change, but these three searches no longer return any results.
Moved the installer library to the new location, with tweaks.
Putting database and session back in autoload.
Adjusting missing table_name references that were missed during the change of Model.
Adding installed.txt to the gitignore file.
Initial install simplification.
Moved install into it's own controller.
Merge branch 'develop' of github.com:ci-bonfire/Bonfire into develop
Merging latest develop branch changes.
Misc. fixes for the install process, mostly making sure that all neccessary libraries are loaded when they're needed.
Home controller now loads the auth library and sets the current user so we can see the link to the Admin area.
Fixed link to admin area on home index page to use site_url().
Removed the install folder and all of it's files.
Removing the config folder reference when setting backup copy of config file during write_config method for #855
Bugfix - Removes extra Edit Title column

The Code Builder would produce two clickable titles when viewing the list of added records to a module, thus breaking the table. There was just a reduntant if statment in view_index.php that I've consolidated.
