add test suite

[sascha_silbe]

A test suite often catches programming mistakes and helps ensuring that a component works as intended. The attached patch has already helped me discover several bugs.

Tomeu wrote in #595 that testing isn't really tied to a particular release, so not setting milestone.

Please note that until #1342 is fixed, a single test suite failure is expected (and shows that it's working as designed).

[sascha_silbe]

Latest version of test suite is in  branch t/testsuite (managed with TopGit) inside my clone of sugar-datastore.

I got these errors after applying #1437 and #1342

Does test requires some preparation in environment or just make check?

[sascha_silbe]

Please try the current version in branch t/testsuite in  my repo.
sugar-datastore requires sugar-toolkit at runtime, so you need to run the test suite via sugar-jhbuild:
../../sugar-jhbuild run make check

Moving that to 0.90 as discussed with Sascha on irc.
