Fixes/improvements

pgusinit

Fixes several regressions in pgusinit:

• Fixes issue where port settings are parsed as decimal, not hex (fixes /mpuport, /gusport, /cdport, etc.)
• Fixes /sbport and /gusport commands not passing through option
• Fixes /wifistatus command
• Restores /defaults command

General

• Gives VREG a bit more time to settle at bootup/reset. Should improve stability on initial poweron, after changing modes, or flashing firmware.
