Fixed / update conda recipes

- fixed problem with new conda by using new compiler mechanism
- added test file that is checked before upload
- open mesh recipe fixed
- force downgrade for conda-build, new tested version(3.2.1) of conda-build leads to an empty
  package and then failing test.. perhaps it is fixed with newer conda-build versions?
