* Modern mamba returns zero on error, and prints its error messages to stdout. FANTASTIC.
* The error detection seems to still handle the previous behavior as well with older versions.
* And now we print the contents of stdout and stderr on a non-zero exit from the package manager

* Use it for conda and libmamapy version detection

* Boa is dead, but we can still use it if conda is old enough
* Also because boa is dead we purge it from the list if the conda version is too new
* Initial environment activation changed as well, but still compatible with older versions of conda

* Rename RECIPE_TYPE_* to RECIPE_STYLE_*
* Add defines for RECIPE_BUILD_* that denote which build system should be used to build the recipe
