in commit 11dcc9cb ("build: remove
autotools from packages spec"). No sense to require autoconf, automake
and libtool to build tarantool.

Tested and updated building instructions for Mac OS X. (by Elena Shebunyaeva)

see https://cmake.org/cmake/help/v3.4/variable/CMAKE_BUILD_TYPE.html

* New brewspec, that gives ability to build latest stable
  (for latest master you need to pass '--devel' flag)
* All dependencies are inside this spec
* We can now test Tarantool (you need to pass '--with-tests'
  flag to 'brew')
* We can build Tarantool with -DCMAKE_BUILD_TYPE=Debug (default is
  'Release')
* Fix for name of pypi module - ('python-daemon', not 'daemon')
* Fix README for MacOSX
