[tycho-dev] No more Tycho

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

Hi Tycho devs,

with the recent changes, Tycho itself do not require Tycho anymore and 
also all former OSGi services where converted to plexus components and 
all test where convertet to plain JUnit/Plexus ones.

Some projects still carry OSGi manifests in their resources folders, but 
that might change in the future as well and these are more static ones 
so nothing one needs to specifically care about, PDE is no longer a 
nature for any Tycho project.

This finally makes it possible to use everything-everywhere and we 
likely can clean up some indirection introduced in the past. We might 
also think about how to split the code base into more better shaped modules.

While this is mostly invisible to our users, it will greatly simplify 
the development of new features.

best
Christoph
