This adds the ability to save link targets or images. The save location
can be default, or the save as dialog can be invoked.
Somewhat sensible default filenames are provided.
Data URLs are also supported (though they need quite a bit of massaging
to get past the WebExt security limitations). Specificially, they need
to be round-tripped though a Blob, and must be saved from the background
context.
This adds an excmd interface to the Web Speech API (TTS), which allows
users to read text out and set voice and parameters via config options.
Excmds:
- ttsread: reads out the given text or element content (CSS selected)
- ttsvoices: lists available voice names (can be used in the
'ttsvoice' option)
- ttscontrol: stops the current reading (should also pause/resume,
but that doesn't seem to work right now)
Config options:
- ttsvoice: the name of the voice to use
- ttsrate: (0.1-10)
- ttsvolume: (0-1)
- ttspitch: (0-2)
Also the ;r hint submode is added which reads the textcontent of the
element with the configured voice
THis yanks the page URL with the hinted elements id or title as a hash
fragment, which can be used to link to the page at that element's
location.
