spaces in repo name gives error

[technophile-04]

Description:

Not sure whats the best way to handle this...And we are kind of already hinting user to use (dashes instead of space in example name)

[carletex]

Maybe we just do repoName.trim().replace(/\s+/g, '-'); ? So we remove spaces at the end and beginning of the string and then use - (or maybe _) instead of spaces in the middle
