 Remove the spaces from the fingerprints.

 This isn't OpenPGP, no one goes around reading them off to people. You
 have to click-hold-carefully-drag to select the whole FP instead of a
 simple double-click. You have to postprocess strip them to make any use of
 them anywhere, including everywhere else in Tor... torctl, configs, etc.
 Nowhere else does Tor present/accept any fingerprints with spaces. And
 they currently waste about 60kB per descriptor set X all the nodes X
 frequency.
 The spaces have no substantive use whatsoever and are very annoying!
 Please remove them.

 With that, normalize all displayed/coded fingerprints everywhere in Tor to
 be either upper or lower case... regardless of whether either/mixed case
 are supported/enforced as input. Lower case is suggested for better
 readability (ie: A4B8D0 vs. a4b8d0) and commonality with outputs of
 various hash programs.
