Added ability to use an execution list as a custom menu in place of the main menu. AutoBoot functions are superceded by this and have been removed.
Custom menu option is no longer limited to the filename 'menu.list'.
'Custom main menu' in settings is now a submenu. Added a couple of list templates.
Note: Due to changes in v1.1.8.5, the 'Update Program' option will break access to the recovery environment. Disks created with a version prior to v1.1.8.6 will need to be recreated in boot creator. 'Update Program' remains functional afterwards. Apologies in advance.
