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  browser for the repository
preview.php  cut down display routine from resource.class.php, forces sidemenu etc.
repository_deploy.php  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
