replaced /tmp with cfg->{tmpdir} - using File::Spec - thoughout app; fixed circular ref in C::Ajax::load_template()

moved authen_config from lims_config.pl to main LIMS app - CUSTOM callback doesn't work when cfg loaded using Class::Singleton instance; modified idle timeout function to automatically load logged-in username in login screen, so only passwd required, and added link to logout if different user; cgiapp_prerun checks form param username matches authen; added region_code back to user_locations + admin functions

moved login.tt from site to login/default.tt; used authen->is_new_login to redirect to C::Login::hello(); moved code to generate new diagnosis list from LIMS::_create_user_profile() to C::Login::hello(); new db table user_message + DB class

moved LOGIN_SESSION_TIMEOUT 'CUSTOM' code to custom_timeout() sub; C::Admin::User::update_user_details() retrieves new user.id to fix (recent) uninitialized val warning in permissions.t; added debug.log fh to L::Local::Debug::DEBUG(); added 'function' object to M::User::get_user_permissions() to save multiple db lookups

authen_cfg LOGIN_SESSION_TIMEOUT sets timeout value according to user location (ie lab staff or guest user)

replaced several calls to L::Local::find_home() with call to config instance; removed call to L::Local::Debug from lims_config.pl, as debug() uses config instance, which uses lims_config.pl; model classes get config from config instance instead of constructor passing it in LIMS::model(); general tidy-up
