Menu is now disabled when there are no detected links in the selection.

It also adds an option on preferences that allows to hide it instead.

This option is not enabled by default because it will cause for the menu to be refreshed and a visual moment that shows the menu being added (it's just a few milliseconds, but it's noticeable)

Corrects bug introduced by some mozilla change on the API.

It nows checks if the selection is a range before retrieving the links

Sometimes when opening a lot links using this extension makes the browser grind to a halt.

Added a limit how many tabs are opened/loading at once.

Now the default maximum loading tabs is 4 (just a nice round number), but the old no-limit functionality is still available if the limit is set to 0. There's also a timeout for tab "loading", so if the tab loads slowly, other links/tabs still get opened after a timeout.

Functionality added by github.com/attekemppila

Add option to set a delay between opening new tabs

Add option to set a delay between opening new tabs

Opens only unique links (thanks to @killemov)
Uses async libraries and small delay when opening links (thanks to @d3m1gd)

Adds `openerTabId` when opening new tab to relate with original, thus allowing for better collaboration with other addons that use this information.

Thanks to @piroor in github that submitted the changes
