Add ability to specify additional URI handlers

This commit adds a new section, open-with, to the configuration file.
The options specified there will be added as "Open with …" menu items in
the URI context menu. This is to make it easier to perform other actions
on the URI than opening it in the system default browser; a user might
for example add another browser, media player, or a script that
preprocesses the URI before opening it.
