We had the legacy "memIndex" option to put the Camlistore index in
memory (the leveldb memdb) as an option in genconfig called
"memIndex", and we also had an option called "memoryIndex" for whether
to slurp the on-disk index to memory on start-up. Too confusing!
Instead, delete "memIndex" (since it's not the default anyway, now
that we have kv).
Then, also (the original point of this change): default the
memoryIndex option to true, so search works for people by default.
This option might go away in the future if it becomes the only required
way.
Also, document this.

Because no localdisk means either s3 or google is the primary,
and none of them support efficient replication.
1) Added a dummy synchandler constructor for when config has "idle"
2) Set "idle" for synchandler config when no localdisk
3) fixed corresponding tests
Also:
- added error (and test) when no localdisk and both s3 and google
in config
- added s3 + mysql test
