* hydra: indentation and fixed duplicate key in cachedgitinputs bug

Dependencies

• [2] BK24VA6Q * for git inputs, check latest revision of branch (defaults to master for now), if there is change, only use input if last checkout was > hour ago.
• [3] Z6XUFUCL Set $NIX_PREFETCH_GIT_DEEP_CLONE.
• [4] JTRG7RDQ add support for git as jobinput
• [5] NJBETZ2C Use $NIX_PREFETCH_GIT_CHECKOUT_HOOK to produce a `.git-version' file.
• [6] OOQ2D3KC * Refactoring: move fetchInput out of hydra_scheduler into a separate
• [7] VN2SV3G2 Ask `nix-prefetch-git' to leave `.git' in the output.
• [8] RR7O4KFU Set $NIX_PREFETCH_SVN_LEAVE_DOT_SVN to 1.
