SI-6766 Create a continuations project in eclipse

We're missing a continuations dependency when we try to build reflect
in eclipse which causes things to die horribly. This commit adds an
eclipse project for the library portion of continuations, makes
projects that depend on the scala-library also depend on
continuations-library, and adds another bullet to the eclipse readme to
turn on the continuations plugin.
