Additional customizations to dialog boxes

[cmdcolin]

The ability to customize dialog boxes was introduced in jbrowse 1.11.3. There are a couple of use cases that still remain that could be added

• Ability to access feature information inside a callback. Currently only the data item that is being customized is available to the callback. This can be useful if you wanted to for example access to ID when you are customizing the name field (to add a link out for example).
• Ability to remove specific fields entirely. This has been requested several times on the mailing list. Also add ability to add a new fields.

"RE: the ability to access feature information inside a callback": This can also help you customize top level features instead of "subfeature" attributes by calling feature.get('type') in your callback

Also, here's a reference of current status of this feature http://gmod.org/wiki/JBrowse_Configuration_Guide#Customizing_parts_of_the_.27View_details.27_Pop-ups_with_callbacks

Added: allow user to access the feature object from within the callback functions

Added: allow user to make mouse over/yellow style box using fmtDetailDescription
Added: disable application of callback functions to the "About track" panel
Added: customizable fmtMetaField/fmtMetaValue/fmtMetaDescription callbacks for the "About track" panel
