Merge doc/unit-tests.md into src/test/README.md

Refer to the right file in the top-level README.md.

Having only one file with test documentation saves some confusion about
where things are documented.

-Compiling/running unit tests
-------------------------------------
-
-Unit tests will be automatically compiled if dependencies were met in `./configure`
-and tests weren't explicitly disabled.
-
-After configuring, they can be run with `make check`.
-
-To run the bitcoind tests manually, launch `src/test/test_bitcoin`.
-
-To add more bitcoind tests, add `BOOST_AUTO_TEST_CASE` functions to the existing
-.cpp files in the `test/` directory or add new .cpp files that
-implement new BOOST_AUTO_TEST_SUITE sections.
-
-To run the bitcoin-qt tests manually, launch `src/qt/test/test_bitcoin-qt`
-
-To add more bitcoin-qt tests, add them to the `src/qt/test/` directory and
-the `src/qt/test/test_main.cpp` file.
