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.
Charting: dates on x axis.
Remove unused :show_title param logic
More chart styling options.
Charting: small style and typo fixes.
Charting: Remove color css attribute.

Setting of the color to white hides important chart elements.
Dry up routing file
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
