Fixed the bugreport component to automatically register all "Oops!"
errors with the ticketing system on the hosting hub. When the
RAPPTURE_VERSION environment variable is set to "current", the
dialog automatically registers errors. Otherwise, it pops up a
dialog showing the error to the developer. It also registers errors
that come from launching jobs ("Problem launching job" messages).
Fixed the Makefile to install all scripts/*.tcl files, so we don't
have to modify configure each time a file is added.
