v0.6.4

There are currently known regressions:

• using RTS together with the distributed backend database is not working

Fixed

• break & continue now works in for loops that are CPS fragmented [#325]
  • Using break would previously not work in a for loop if the loop was
    broken into multiple continuations during the CPS transform. For example,
    this happens when a call to another actor is made in the for loop.
• An installed actonc can now find __builtin__.h [#327]
  • A previous restructuring of files in order to improve the Makefile and build
    organization led to us having to use weirdly long and relative include
    paths. This ultimately led to run time failures of actonc. Since some of
    these files need to be built both when building actonc itself as well as
    when using actonc, the paths must remain the same in source and release
    output. They did not after [#286], which has now been reverted.
