Improve user interface

[Yamakaky]

Hi

What a software ! It can be used for really cool thinks, like sharing user data between multiple computers, like in a small enterprise, so that it doesn't need a central file server, + store-only remote backup !

I have some user-interface improvements I would like to submit you :

• use GNU style cli options : a lot of softwares use it, it's well established. -help is strange XD. --version and --help are better ^^
• -useLPD=true -useDHT=true : if they have to be used every time, why aren't they on by default ?
• -gen could be launched if there is no id provided, with the readwrite permission.

Thank you for the kind words !

• -help does feel strange indeed, but that's what the stdlib gives me, so I take it. There has been effort to achieve what you're after; I may have a look at it when the more urgent things are there
• DHT and LPD are false by default because that's how it was before and there could be concerns about privacy. I will make these both on by default.
• I like explicit better than implicit. I'd prefer if people used -gen to generate ids, so that it's easier to remember how to generate these ids. For consistency though, the share mode should be available through a -share flag.
