* Changed the way temporary variables work. They won't be unset before

a command is executed anymore. Instead the least recently used
  temporary variable is overwritten, if there's no free slot for a new
  temporary variable.
* Removed the special handling for the command result variable ("_"). It
  just works like any other temporary variable, now.
* Individual temporary variables can be removed (e.g. using the "unset"
  command).
* Added unset_all_debug_variables() and "unset_all" command to unset
  all persistent and temporary variables.
* Removed remove_all_temporary_debug_variables and renamed
  remove_debug_variable() to unset_debug_variable().
