Error handling

[Eneroth3]

As a new users I've done a few errors and was thinking it would be helpful with some improvements in error handling.

If the library you are trying to install lacks a tag with version info you get an error message saying "Found no version ''" (first error in attached screenshot). I had to find the error in the Skippy source code to figure out what it meant. It would be very helpful if the message stated where Skippy expected to find a version of what, i.e. as a Git tag in the library.

Perhaps this could even just be a warning, not an error being raised. I noticed that if the versions defined in skippy.json and as a Git tag differed only a warning was given.

After adding the tag to my repo and trying again I got a second error (also seen in attached screenshot). It seems the last install attempt copied all the files over into the extension skippy/libs directory, even if the library wasn't added to the list in skippy.json, and later installing into a "dirty" directory causes a failure.

Maybe clearing the target directory of any files before installing a library could solve this?

Yea, there is work to be done on error handling. Right now it's just a proof of concept - so the focus have been on the happy path. Once that has been refined attention will be made to catch failure cases.
