Log Message:
Update devel/ruby-debug-base to 0.10.1.  Changes from version 0.10.0
include:

 * Allow catching multiple exceptions.

 * Add Debugger.last_exception which is set in post-mortem.

 * Remove Debugger.stop() when an exception is raised that would
   terminate the debugged program. This may allow catchpoints to work
   and allow tracing user code which handles "Exit" exceptions

 * Preface ruby_debug global Ruby variables with rdebug_.

 * Change Debugger.start() to accept an optional options argument
    :init => true saves things (like $0 and ARGV) necessary to
     allow restart. Default: true
    :post_mortem => true runs post-mortem on an uncaught exception
     Default: false
   The old Debugger.start() is now renamed to Debugger.start_()

INCOMPATIBLE CHANGES:
 * variable "Debugger.catchpoint", a String, was turned into
   "Debugger.catchpoints", a Hash.
 * Method "Debugger.catchpoint=" no longer exists.
 * Debugger.set_catchpoint was turned into Debugger.add_catchpoint
 * return/end will now call event handler
