#493 gaussformat should use high-precision normal modes if there

[Michael Banck]

Gaussian can optionally print out normal modes with 4 (or 5?) decimal digits in addition to the regular 2 digit normal modes if the "hpmodes" option is passed to the "freq" directive.

OpenBabel should parse those instead, if available

Cam you supply me with an example file? If so, I can add it quickly. Thanks!
