cache: Introduce StringCache, switch to unordered_map, default to memory cache if fs cache dir not given

Any small change on a page "updates" the feed, which is misleading to clients.
May need "minor edit" or something. For now, get rid of it.

+Some essential features are lacking, such as a diff between revisions,

+
+It doesn't compete with any other software anyway.

 Dependencies:
   - cpp-httplib: https://github.com/yhirose/cpp-httplib

 The first three are header-only libraries that are included as a git submodule. The others must
 be installed, e. g. by using your distributions standard method.
