My old kphotoalbum database is no longer relevant, rphotos is
the main soruce now and should not be overridden.
The readkpa subcomand was never intended for general consumption
anyway, it was hardcoded to match configurations in my kphotoalbum
setup.
Thirty days is max expire time in memcache, setting a larger value
gets it treated as a unix time (so when I said 90 days, everything
expired april 1, 1970).
Also, less logging while precaching.
Use static files handling from updated ructe rather than local
handling, and use rsass rather than sass-rs and sass-sys.
Static files are now kept in the binary (no more need to access the
build directory at runtime). Also, there is an admin command to save
the static files to a directory, for the benefit of fronting web
servers and backwards compatibility.
