Added versions of the debugger trap commands that trap on all mirrors,

not just the specified address.

     Thanks to Omegamatrix of AtariAge for the bug report and patch to fix
     the issue.
 
+  * Added 'trapm', 'trapreadm', 'trapwritem' commands to debugger prompt.
+    These are similar to the non-'m' versions, except that they also trap
+    on all mirrors of the given address.
+
   * Fixed bug in debugger 'reset' command; it wasn't resetting the
     bankswitching, so after a reset the banks were in an undefined state.
