Fix the Uguu uploader and SICP crash on no auth

[handlerug]

Note: I have no idea whether Host.Type.POMF and Host.Type.UGUU should really be called after pomf and uguu; I'm too late to the pomf.se party to know who was the first or what was the standard back then. However, pomf.cat and uguu.se seem to be based on a single codebase (and both use files[] not file), while sicp.me is different (uses file). So maybe the enum constants should be renamed.

Also, in uguu.se gyazo and text response types are synonyms, but I put gyazo in to be consistent with the pomf.cat definition.

Also, it seems like hostings supported don't exhibit the weird behavior described in the extractUrl function, so maybe it should be ditched altogether.
