Respect atom type when converting rate tag (#896)

* Respect atom type when converting rate tag

TagLib prior to #818 (commit ff28cf276c60) read and wrote the "rate" tag as
text, and switched to reading it as integer value even when the atom class
is a text type. This breaks reading existing files, and can be avoided by
taking the atom type into account.

This fixes issue #885.

* Respect MP4::Item type when writing the rate tag

TagLib prior to #818 (commit ff28cf276c60) read and wrote the "rate" tag
as text, and switched to writing the integer value of the MP4::Item.
This breaks writing from applications which supply the value as
StringList, which was the previously implemented API. Applications using
an MP4::Item(UInt) are still supported without changes on the application
side.

This is the complementary writing part for issue #885.
