Remove superfluous artifact sync output from bob build, enable detailed information using the verbose flag.

[zuzuleinen]

Todo

• Remove superfluous artifact sync output from bob build
• enable detailed information using the verbose flag.

Example of the current output which looks kind of messy:

$ bob build 
Using remote store: https://bob.build/xxxxxx/xxxxx
Warning: possible version incompatibility: Your bobfile's version (0.6.1, 'ui') is higher than the CLI version (0.0.0). Some features might not work as expected.
