Prepared documention for upcoming 3.0.0 release

* Renamed folder ``user`` to ``2.0.x``.
* Created folder ``3.0.x`` and merged documentation of ``2.0.x`` and ``helium``.
* Removed references (i.e., :ref: links) because they cause ambiguity when the same
  label is defined twice (not surprisingly). Use :doc: instead, and always use relative
  paths!
* Created a symbolic link ``current-user-doc`` that should always point to the user
  documention for the current stable release. The intention here is to avoid absolute path
  to the user documentation from places such as tutorials. The symbolic link should point to
  folder ``3.0.x`` as soon as we release the Scala IDE v3.0.0.
Updated changelog with tickets fixed in 3.0.0-RC2 and RC3
Merge pull request #46 from scala-ide/prepare-3.0.0

Prepared documention for upcoming 3.0.0 release
Removed one more label.
To prevent breaking all links to the doc in the scala-ide.org website, I'm
adding a symbolic link from `user` to `2.0.x`. This symbolic link should be
deleted when we prepare the website for the 3.0.0 release.
Added Maven tutorial.
Fixed spelling mistake in the Maven tutorial.
