Issue #30: Add onClick, accesskey, and tabindex tags to Image Map plug-in
This patch attempts to resolve (the 21+ year old!) issue #30 (closed).
It adds two new fields to the HTML Link tab and one new field to the Javascript tab for area properties:
- accesskey: The same as the mnemonic key shortcuts in GTK, to activate an area of the image map. Depending on the OS, you either hold ALT or ALT+SHIFT and this key.
- tabindex: What order to select the area when the user presses Tab.
- onClick: Run a Javascript function when the user clicks on the area
I also updated nearby code to the current GIMP coding style.
