v0.2.1

• Actually offer all files, don't skip the first one.. (this issue was introduced when adding subcommands)
• Revised README to tell more precisely about security
• Use local time zone in logging
• Increased sync timeout; this seems to be needed for slow homeservers
• Much more efficient first sync after startup, makes use of the token from the previous session
• Do the emoji verification before log room setup
• Offers are now a bit more revised to look like the final product, added thumbnails and SHA512
• Better help texts
