Manticore 5 support about rats-search

[CGretski]

After making a copy of database folder (to manticoredb) I have successfully used version 1.9.0 with a standalone instance of manticore 5.0.2 on Windows with no real problems.
"d:\manticore\bin\searchd.exe" --config d:\rats\data\manticore.conf --pidfile

There is an error in rats.log during startup, though it doesn't seem to affect anything:
[12:25:29] founded running sphinx instance in D:\rats/data/searchd.pid, using it
[12:25:29] changed configuration user directory: undefined
[12:25:29] [ERROR] Rejection: TypeError: Error processing argument at index 1, conversion failure from undefined

[12:25:29] external sphinx signalled
[12:25:30] db version 8
[12:25:30] db patch done

My config file is attached:
manticore.conf

Notable changes from original sphinx.conf:

• workers directive no longer exists
• configured empty "stored_fields" on torrents index as default for stored_fields is now all full-texts fields.

For performance tuning on my machine I also configured rt_mem_limit on the files and torrents indexes and disabled psuedo_sharding.

I created branch with manticore5 support, need also some additional changes to handle it properly
