All the changes for 2.6.0!

	* [Bug] Minor bug in the updater template.  Needed to use version_compare instead of "<="
	* [Bug] The "disabled" form attribute is now better handled on both the renderer and the parser.
	* [Performance] Applied more aggressive compiling on the bootstrap.  Gives a little bit more
	  performance.
	* [Feature] New feature - /form/savetemporary.ajax, this is a page that will save a given submitted
	  form back to the session as an auto-save feature.
	* [Feature] Added a new form element, FormPageMetaAuthor.
	* [Feature] Added a new form group: 'FormTabsGroup'.  This uses javascript to render out a tab-based
	  layout.
	* [Feature] Added support for FromGroups to be mapped via name.
	* [Feature] Implemented Feature #385 - Sanitize filenames for files uploaded
	* [Feature] checkbox groups now have a toggle all option
	* [Feature] Added a "keepdots" parameter to the str_to_url function.  Useful for filenames
	* [Feature] Major rewrite to the page form elements.  The PageModel is now responsible for all of the
	  elements rendered out.
	* [Feature] Disabling components now actually removes their user configuration options and pages from
	  the system; (enabling re-adds them back).
	* [Feature] Disabling and enabling components now register in the security log.
	* [Feature] The site is now locked automatically when the automatic reinstaller is initialized.  This
	  prevents the site from dropping into multiple reinstalls at once.
	* [Feature] FilterForm now supports "linkvalueprefix" and "linkvaluesuffix".  These get prepended and
	  appended automatically to any value; useful for datetime strings.
	* [Feature] Widget instances and Widgets now can keep track of which "installable" tag the widget was
	  called with.  This allows metadata to be passed into the widget.
	* [Feature] Added 'Performance' to the list of changelog types.
	* Updated the documentation on all the Form elements.
	* New method, Template::getInsertables.  This has been moved from the page element system to the
	  template system where it belongs.
	* New method, Form::addElementAfter.  This allows an element to be insert into the Form after another
	  element.  Useful for Form manipulation.
	* New method, Form::getGroup.  Will search through the element list for a given group by its name, and
	  create one if it doesn't exist.  Takes into account the Group type too.
	* New method, Form::getModels.  Just returns the unaltered models associated to a Form.
	* Form::addElement now supports the attributes "group" and "grouptype".
	* The Form system now skips automatic form handling on any /form/*.ajax page.  This allows those pages
	  to be submitted to directly to act as metafunctions for forms.
	* Models with existing data can now have a UUID column added.
	* Insertables are now better linked to the given page's site.
	* Rearranged the title and parenturl for pages.  This allows the basic information to be displayed
	  first.
	* System form elements now jsonencode their values.  Allows multi-values to be used in the unique key
