Preliminary preview release v0.0.1

This is a preliminary preview release, intended mainly for playing with z-scratchpad and experimenting with it, certainly it is not yet ready for usage.

That being said, I do personally use it everyday, so at the moment it seems to be working at least for me and it didn't drop my entire notes collection... (Although I do have it versioned...)

Most commands work as expected, although most likely there might be quirks and errors in various corner cases. The server command does work, but the used CSS is just a "reset" one, thus the resulting page looks broken.

The tool is very strict about inputs and assertions, thus it will easily bail out with an error... Unfortunately at the moment the error messages are composed just of codes; to know what is wrong one has to grep the source code for that.

I've built binaries for Linux, OSX, FreeBSD and OpenBSD; however, only the Linux one was tested. The others might work; if they don't just open an issue describing the problem.
