• Fix bug in generated nix expression
• Fix bug that prevented targeting tags with prefetch command

• Remove dependency to requests
• Default to master branch instead of first branch in list

• Add --version flag

• The result of nix_pretch_github and its corresponding command line tool now contains always the actual commit hash as detected by the tool instead of the branch or tag name.
• Add a new flag --nix that makes the command line tool output a valid nix expression
