Thanks for addressing this long-awaited deprecation of AeroDyn v14!
ElastoDyn blade input PitchAxis was only used with AeroDyn v14. Now that AeroDyn v14 has been removed, PitchAxis should be removed from the ElastoDyn blade input file.
This PR addresses issue #93.

- Regression tests with AD14 converted to AD15, but not tuned correctly yet. - update docs to not mention AD14 - update error handling in parsing .fst files
There were comments about ADAMS still in this. Nothing about AD14 though.
These test cases were unstable with AD14 and did not correspond well when upgraded to AD15. Thus we decided to simply remove them for now.

Feature or improvement description
The AeroDyn14 module was a carry-over from FAST v7 to FAST v8 as a stop-gap while AeroDyn15 was under development. As such AeroDyn14 was never converted to the FAST Modular Framework; this created many code workarounds in ElastoDyn and in the openfast-library to get it to work. At this point AeroDyn15 is far more comprehensive than AeroDyn14 so very few users ever use it. Therefore the plan for many years has been to remove it entirely, and now we finally got around to it.

Impacted areas of the software
There are some significant improvements to the glue code and ElastoDyn with the removal of AD14.
Several code development projects are depending on this PR.
CompAero==3)CompAero==1)Additional supporting information
The regression tests that previously used AeroDyn14 have been updated to AeroDyn15, but have not been tuned correctly for the DBEMT parameters (in particular the
Tautime constants). Some of these cases also show instabilities and had been turned off as a result. We need to decide which cases we will simply remove, and which we will keep.Test results, if applicable
