Automate FileMaker data upload

[rednaw]

What we have:

1. Manually create export files using the FileMaker export functionality, one for each table (FM database)
2. Commit cleaned files to Git

What we want instead: A single command that does both steps in one go without clicking in the FileMaker UI. It should be possible to run this script locally on a Mac with FileMaker installed.

Step <1> can be automated in one of two different ways:

1. With the builtin FileMaker scripting functionality
2. By letting a script connect to FileMaker using ODBC, for instance with Ruby/DBI
