The current MailMate EagleFiler archive script works with the top-most open library, but we'd like it to work with a specific library.

## add Bash Shell Script

* Add line 10, env var to specify path to the `.eflibrary` file.
* Add on line 14, an arg 3, using that var.

## EagleFilerImport.scpt v2

* Add a third `_argv` on line 3.
* Add line 9 to open a POSIX path pointing at the library we want to open.

## To Do

* Store the posix path within MailMate. How? Maybe `defaults write`?
