Removes unwrap and returns a Result instead of panicing if an invalid
path is given.
Previously if the flag: '-x' was provided with an argument of an
invalid directory the code would crash here

Add optional -x flag to limit search to the current filesystem.
Add (untested) support for windows for the equivalent of inode and
device.
* Initialize ansi_term if we're on windows
* Silence build warning on non-unix targets
* Update ansi-term which has windows specific fixes (and assert_cli while I'm at it)
Advised to use walkdir by burntsushi as using recursion on file systems
can blow the stack.
walkdir is slower but allows the code to be cleaner and more reliable
Also experimented with ignore but locking the hashmap resulted in
similar performance to walkdir but with much uglier code.
