ObjectScript Code

add `pkg.xml.encode()` utility, and make `pkg.fs` more consistent w.r.t. accepting files or paths

fix for extracting the lib files... by the time the build is done, the plugins are packed as .jar files for pushing to the update site. So we need to mount the .jar file and copy the .jar files it contains. Plus fixes to get rid of warning messages in the customBuildCallbacks.xml and addition of pkg.fs.wpath() API for getting a platform native path

sync up build script with latest from PLATO repo (build script re-use ;-))

fix problem in analysing copy history.. the trunk can be the common ancestor

some debug logging for pkg.svn

some hacks to properly handle windows paths

add support to pass a directory to `pkg.runtime.exec()` to execute from the context of a specified directory

add script-editor plugin

we should avoid swallowing exceptions that aren't `NoSuchMember`

error handling for silly windoze bugs
