Successfully parsing output of security(1).

Found some cases in output that original tests weren't catching. Fixed.
Added parser error check to prevent infinite loop.

Added check to make sure we don't try to parse a single line more

there's a bug. Rather than hanging, bail out with an error.

Split keychain access into separate file.

Started building out cache. Keychain access in separate file.
Updated keychain parser tests to use keychain module instead of
calling /usr/bin/security directly.
