1. Added logic to process repository paths. A repository path is marked with a # as the first character of the reference field.
2. Added a new error code for repository items not being deployed / bad reference.
ims.html change:
Added a button to link to the repository browser.
New files:
finder.php \96 browser for the repository
preview.php \96 cut down display routine from resource.class.php, forces sidemenu etc.
repository_deploy.php \96 deploy for repository items (same results as deploy.php)
repository_config.php (repository disabled by default)
resize.js - for iframe resizing
dummyapi.js - dummy SCORM API
(Tom's work, with help from Andy)
