Feature: dump memory region to file

[UCSIG]

This adds the option to dump a memory region to a binary file using the dump command. If the file specified in the command already exists, it doesn't overwrite the file, only when the --override option is specified.

I couldn't figure out how to make the --file option an optional argument, thats why I specify the default value as an empty string and check in the command handler if a different value than an empty string is present. Maybe you know how to make the --file option an optional argument instead of a required argument with a default value?

IMHO, --overwrite seems meaningless. Almost all command line tools overwrite if filenames are provided.

Merged.

• remove --overwrite
• rename to -o/--out
