Track No. and Year not treated for null values

[viper21]

When the track number and/or year tags of a track are "null", they appear with value "0" in:
(1) Tag display of Now Playing view
(2) Tag Editor
To be more accurate they should display without any value.
And as a relatee issue, in the Tag Editor, one should be able to enter nothing as a value for these tags and then not have them display "0" as their value.
Would be happy if you could fix this minor issue.
Thank you.

taglib, the tagging library gmmp uses treats both of those tags as integers.. so null is not a possible value for them

/*!
* Returns the year; if there is no year set, this will return 0.
*/
virtual uint year() const = 0;

/*!
* Returns the track number; if there is no track number set, this will
* return 0.
*/
virtual uint track() const = 0;
