Subject: Format of gmkin workspace files, copyright, updates

- Change the format of the workspace files of gmkin so they can be
  distributed in the mkin package
- Add gmkin workspace datasets FOCUS_2006_gmkin and FOCUS_2006_Z_gmkin
- Restrict the unit test with the Schaefer data to parent and primary
  metabolites as formation fraction and DT50 for A2 are higly correlated
  and passing the test is platform dependent. For example, the test
  fails in 1 out of 14 platforms on CRAN as of today
- Add Eurofins Regulatory AG copyright notices
- Import FME and deSolve instead of depending on them to have cleaner
  startup
