Much improved handling of problematic Bower dependencies

1) Added a capability to override or ignore problematic dependencies via a set of new config flags.
2) Added new handling logic to cope with unsupported complex package versions and "*" paths.
3) Added an extensive post-download diagnostic report telling what dependencies have been altered, ignored or remained unresolved, with instructions on how to manually fix or override that.
