fefa560017 Change addons subproject to use .addons-dont-touch directory instead of addons 
This hides the directory name under standard invocations of ls and thus avoids confusing the user with extra directory names.

69d765744c Adjustments to the build structure (see below) 
All 'addon' subprojects now have their sources aggregated into the addons subproject. This is done via a source copy (so that sbt will only rebuild sources that actually changed). To prevent caching issues the addons/src directory is CLEARED and then refilled every time addons is compiled. Thus, it is CRUCIAL NO SOURCES ARE MANUALLY ADDED TO addons/src AS THEY WILL BE WIPED BY addons/prepare. Due to sbt source caching, sbt will still be able to tell which sources have changed. (Strangely, sbt would not cache sources in extra unmanaged source directories and thus would always recompile them.) Also, cleaned up project/build.scala a bit to remove some warnings: Added import scala.language/postFixOps (so make! at the bottom no longer errors) and .toURI.toURL (as straight .toURL has been deprecated by the java standard library).

a999c055ed Don't take an interrupt when EX stage PC is invalid 
It was possible to take an interrupt on the instruction in the shadow of
a short forward branch.  EPC would thus get the wrong value, and so
a wrong-path instruction would be executed upon return from interrupt.
