[Feature Request] Search by pinned sources

[xdeiimoss]

What feature should be added to Suwayomi?

In mihon, there's two types of searches (which works on both global searching and migration searching)
You can search by pinned sources and by all sources. Also, by choosing one of the types of search, it will always search by the last type used. Eg: Last time I used pinned, it will use pinned next time
