1) Lua Tarantool Server, that runs plain lua code and admin server commands (separated ';\n')
2) Python Tarantool Server, that runs old plain tests.
Also created Two types of tests, that inherit FuncTest (Cause they're FuncTest):
1) LuaTest -> Lua Tarantool Server
2) PythonTest -> Python Tarantool Server
In the future we plans to add luabench as one of Test types
Rename all cores to appropriate names of server (now it's 'lua tarantool' and 'python tarantool')
Prepare to remove lua prefixes (if you need to test wrong or nonimplemmented command you may run 'admin('cmd', simple=True)')
If you want to implement new server command - add needed regexp to admin_connection.py.
if it's fixed length command, then add it to rg1, else rg2

cardinality is how many unique elements a set contains. wrong term
for the max number of fields in a tuple

Hat tip to Alexey Panfilov

Make w3c isopub.ent entity files available locally,
since it is part of nobody-knows which package on Ubuntu,
and may be missing completely on other distributions.

On Ubuntu 13 even though it is part of mathml, it's not listed
properly in /etc/xml/catalog apparently.

This fixes xsltproc warnings and speeds up manual generation
significantly.

Remove the regression I introduced when trying to be to smart when
comparing integer numbers.

Numeric comparison is not memcmp compatible on x86, and I don't
know what I was smoking when I wrote a test which proved it wrong.

Conflicts:
	test/box/socket.test

Apparently until I stop bullshitting ppl in the tagline I won't get
my hands on to finishing this feature (been 6 months since it was on a
branch).
