Aastra 57xx softkey definitions

[was2]

Hi there,

Looks like aap9xxx6xx/prgkeys.json reflects a full compliment of softkey types for the lower end phones (6731i in our case) while topkeys.json & softkeys.json are missing several types (eg. speeddialtransfer, several others) Is there a reason for this? Seems like I could just add copy those entries over...

@was2 I don't have any aastra phones to test, but send a pull request with the changed file and we'll figure it out!
