exported track filenames are bugged

[joeloc]

locus removes too many chars from track names on export! all my tracks are named like
2011-01-19-Tindaya
2011-01-20-PicoNieves
2011-01-21-Bananarama
...

Locus kills the "-" char when building the export file name and does "20110119Tindaya.gpx" Why? I want it, I need it, and Android has no problem with "-" in its file system, none at all :-).

support for '-' added
