As the sole author of the library and service, I elect to relicense the
code that I have written from GPL-3.0 to MPL-2.0. This is to preserve
copyleft-ability while permitting linking of pop-launcher's libraries.
The launcher binary and its plugins shall remain as GPL-3.0, as they are
separate binaries with no need for linking to a frontend.
Adds an additional parameter for prioritizing the search results from a
specific plugin. The plugin may define a priority which will sort
results after the initial pattern search. The web plugin will be the
first plugin to utilize this feature
