[mythtv-theming] Textedit sizing

[Otto Kolsi]

While working on MythMusic CD rip screen alignments (#6607), I tried to 
make the textedit for year smaller. In music-ui.xml this is defined now 
like this:

<textedit name="year" from="basetextedit">
     <position>370,230</position>
</textedit>

I changed "position" element to "area" and tried different sizes but 
that didn't seem to work. What's the way to make the year edit in this 
case smaller? This should be fairly easy stuff, but I don't know much 
about theming or MythUI as you can see :)
