- provides basic info on positions received/stored in a cluster run,
useful to judge performance.
- document most cluster functionality in the readme.md

This addresses partially issue #1911 in that it documents in our
Readme the command that users can use to verifying the md5sum of
their downloaded tablebase files.
Additionally, a quick check of the file size (the size of each
tablebase file modulo 64 is 16 as pointed out by @syzygy1) has been
implemented at launch time in Stockfish.

I tried to improve the Readme because many people in my local
chess club do not understand some of the UCO options properly.
Starting point of this was Cfish's Readme by Ronald de Man,
some internet resources and the Stockfish code itself.

There is no need to make this as large as 65536 just for the sake of the
single 7-man tablebase that happens to have the key 0xf9247fff. Idea for the
fix by Ronald de Man, who suggested simply to allow more buckets past the end.
We also implement Robin Hood hashing for the hash table, which takes the worst
-case search for full 7-man tablebases down from 68 to 11 probes (Also takes
the average probe length from 2.06 to 2.05). For a table with 8K entries, the
corresponding numbers would be worst-case from 9 to 4, with average from 1.30
to 1.29.

Add Travis CI support to GitHub repo.
After every push to master, Travis will build
the sources directly from GitHub repo according
to .travis.yml and verify everything is ok.
No functional change.
Adds support for Syzygy tablebases to Stockfish. See
the Readme for information on using the tablebases.
Tablebase support can be enabled/disabled at the Makefile
level as well, by setting syzygy=yes or syzygy=no.
Big/little endian are both supported.
No functional change (if Tablebases are not used).
Resolves#6
With the new automatic setting of split depth
instead of a default, the user no longer needs
guidance on setting the split point.
Also threads now defaults to one.
