#7

- updated all versions to 1.2.0. This should have been done after last release.
- changed poms, feature.xml and updatesite category.xml to build 1.2.0 based on Eclipse 4.4 and tycho 0.21.
- created job "swtbotspy_build" on Jenkins which builds branch "#7" after merging it into "master".
- Build succeeded and updatesite has been deployed as expected.
