Summary: implement support for "reload" command in simulator

Initial Comment:
IMHO, it would be useful if there was a "reload" command that would reload the COD-file, this would facilitate reloading a changed image, without having to restart the simulator. So, something along the lines of a "reload" instruction would make the develop/assemble/debug & sim cycle somewhat.

The reload command could simply maintain a timestamp & MD5 hash of the last-loaded image file, so that this would trigger a notification if that changed (i.e. due to rebuilding).

reload without args could and probably should by default fall back to the
currently active filename

given that "reload" would merely be another name for "load
[current_filename]" this could be easily implemented by doing something
along the lines of:

1) automatically set a symbol such as "settings.current_filename" to
contain the path&filename of the the last loaded file
2) provide a new instruction to allow commands to be aliased, i.e. named
"alias"
3) allow commands to access the symbol map and read/write corresponding
properties

so, that you could simply end up with something like:

alias reload="load $settings.current_filename"

Thus, resulting in a new command being added to the interpreter, which is
an alias that's looked up and converted into its native equivalent.

Due to the nature of this request and its simplicity, I normally wouldn't
have suggested this, however I feel that such a facility might indeed be
useful for various other purposes, too.
In particular, because you could have some file which contains your
aliases that may be loaded automatically during startup.
Having something like this in place would be pretty powerful, in
particular if it allows you to directly work with the symbol table

you may not be aware of it (it's probably what most people would call a
"feature"), however issuing "load" multiple times in a row -using identical
filename- will essentially result in "reloading" the active file ;-)

if implemented, it would also be a good idea to honor this information
(the hash that is) when the simulator is "reset", so that IF that hash
should have changed, the user is automatically informed about this and
asked whether he wished to reload the image from disk
