Configure how hashes are displayed and copied

[Kade-N]

Currently, hashes are displayed in the format FFFF FFFF (2B97 8C46), and copied in the format FFFFFFFF (2B978C46).

Add configurable options for the following:

• Use lowercase instead of uppercase (2b978c46)
• Toggle space between words
• Add 0x in front of hash (0x2B978C46)
• Place name in front of hash (crt 2B978C46)

These options will need to exist independently for both status bar display, as well as clipboard copy.
