Compare the .instrument environments of two files

1	CompareInstrumentFiles(file1, file2, ...)

`file1`	A file containing an instrument environment
`file2`	Another file containing an instrument environment. If not provided, `file1` will be compared against the currently loaded instrument environment.
`...`	Arguments to pass to `all.equal.instrument`

This will load two instrument files (created by saveInstruments) and find the differences between them. In addition to returning a list of difference that are found, it will produce messages indicating the number of instruments that were added, the number of instruments that were removed, and the number of instruments that are different.

A list that contains the names of all instruments that were added, the names of all instruments that were removed, and the changes to all instruments that were updated (per all.equal.instrument).
