Changes to set priority for params & show focus on input name in form.

- Changed code to not focus on method data code mirror textbox. Code mirror partial was set to always put focus on code mirror text box. When adding a new input parameter for a method, controller sends down JS command to focus on parameter name text field which was not working as when replacing the whole screen code mirror field focus was taking over.
- Added code to set a priority as last for newly added input parameters so they are displayed in same order as they were added on screen.

Fixes #1082

This is related to the workaround put in for RAILS bug
https://github.com/rails/rails/issues/17466

The code was expecting all values to be present in the
ae_instance.ae_values, the import/export only add non-empty values.
The UI seems to add all values even if they are empty.
So in a new database after the import/export only non empty values are
present as soon as you save it in the DB all values get added by the UI.
If this is a issue we can open a separate git issue for it.
Avoid DOM id conflict by prefixing AE endpoint selection buttons.

Fixed the Right cell text in the Import/Export Accordion in Reports

Clicking on the Upload button causes the form to refresh (another case
of a non-AJAX Upload button) and display the "Custom Reports" caption
twice. This was fixed by setting the correct value in @right_cell_text
