Change time read back to read twenty instead of two-zero on ident.

[allebb]

At the moment, the repeater time read back reads times back as (in example 20:31):

two-zero-three-one

instead of:

twenty-thirty-one

This can be fixed by adding another method to read number back, this should return an array of file names to use 2x.wav instead of 2.wav.

This is now working great, this issue can therefore be closed.
