Minor fixes

[vlad-x]

0. let's rename the project to unit-cli (lowercase U) 😃
1. use process.cwd() as the current path when suggesting the path first time
2. don't ask the server during setup (just assume https://unitcluster.com by default)
3. watch for new/deleted files
4. why is daemon true by default?
5. make a helper function to construct URLs (DRY in runUrl, printUnitLogs)
6. don't use quotes around simple field name (e.g. 'Authorization' -> Authorization)
7. make it possible to run units separately i.e. running unit-cli filename[.js] (.js - optional) will synchronize unit filename (create if new, deploy if not deployed) and run it in unitcluster
8. sometimes local unit code becomes empty (bug)
9. didn't synchronize private units (bug)
10. Text changes:

• Intro:

Hi! It seems you're runing unit-cli for the first time

11. Make a readme and let's publish to NPM! 🎉
