%%PATTERNDEFS%% name is not customizable

[Pascal Leclerc]

The %%PATTERNDEFS%% variable always expands to tt_pattern%d. There should be a mechanism to specify a naming pattern for all expanded fields, eg.: %%PATTERNDEFS(tt_%%NAME%%pattern%%PATTERNID%%)%%

This is really needed for cases where multiple songs are included in the same build.
