Integrate bundle help files with core help

[Greg Couch]

Start by modifying help URLs to work with help in bundles: help:user/commands/cmd_name.html would look in the bundle for cmd_name.html. Likewise for help:user/tool/tool_name.html. Others? help:user/format/format_name.html?

Autogenerate list of all commands? Combined search index? Could have combined list when downloading list of all bundles, and go to ChimeraX Toolshed website for uninstalled tools.

Done. User manual index is automatically augmented with additional tools and commands. Bundles, whose documentation is independent of the core, should have a docs/tools/tool_name.html file and/or a docs/user/commands/command.html file included in the bundle (see the tut_gui and tut_cmd examples).
