Fix Issue #13: Unprovided IProxyService
- Fix broken HTTPS handling.
- Removed checkstyle and findbugs plugin because:
 - to build this stuff you will need Eclipse anyway (PDE)
 - the findbugs-maven-plugin is extremely slow (2 sec per module)
 - The checkstyle and findbugs natures are configured which are way more
convenient.
Added target platform for windows development.
