FR: keyboard shortcut to open extension page, auto-focus omnibox

[pickx]

the URL bar search integration in Firefox has always been a little cumbersome (due to Firefox limitations?), however the omnibox-like search bar in the extension page is imho a better experience and achieves parity with the Chrome extension.

I'd rather just use this omnibox all the time, especially with #229.

the following changes would improve my workflow:

1. add customizable keyboard shortcut for opening the extension page
2. auto-focus the omnibox when opening the extension page (maybe make this behavior optional?)

thank you for this extension

Glad you like my extension.

Yes, I added the search omnibox to the extension page to help users whose address bars don't work as expected.
I'll add support for auto-focus and keyboard shortcuts later.

I think if you were to support this alternative workflow, an option to also completely disable recognition of the rs prefix in the url bar would be helpful.

(more idea dumps for this potential feature)
the auto-update notification page, which may appear when opening the extension page if any crates were updated, should be tweaked to handle this workflow. right now it opens to a omnibox-less page to inform the user that crates were updated.
