Select options can be provided using one of three different methods:
1. key=value pairs, one per line, as for a selectbox
2. @filename.php - The file must be in the egw root, and define an array named $options, that has key => value pairs
3. Define the options normally used for the AJAX Select widget (get_rows, get_title, id_field) and it will pull values from the database, as normal.
Other options (icon, filter, template, link) can be used regardless of the method used to get the values.
- Stop search on up/down arrow, so you can use them to go through results again
- Cancel search timer on up/down arrow
- Pull key codes into a separate array so they're easier to maintain
