jbanana | Jemi progress, part 3

I fixed zooming the text because it was infuriating to have tiny text all the time. I added a cache. I've got to the point where I can actually use Jemi to read content in Gemini space and only several aspects are broken (not all aspects). It was frustrating that it didn't work at all. Now it's frustrating because it almost works.

Bug list: relative links sometimes go to wrong place; not handling external links - HTTP, etc; back button... doesn't; location bar doesn't work; non-text responses... should what?
