Rename FAST to OpenFAST in source

[rafmudaf]

This pull request selectively renames occurrences of "FAST" to "OpenFAST" in order to more accurately reflect the transition from FAST 8.16 to OpenFAST v1.0.0.

The following occurrences have been renamed

• Messages to the user printed through stdout (the console)
• Print statements in the results files
• Compiled executable and binary names
• High level source code file names

The following occurrences have not been renamed

• Low level source code file like module names, function names, errors, etc
• The FAST Registry
• Anything in modules-ext

The code in pull request #107 have been incorporated here, so thanks to @ NobuhiroKUSUNO for the help. Also, this pull request is a dependency of #105.

Please see the regression test results below for this pull request. Of note is the there is an existing bug in the BeamDyn unit tests, beamdyn_utest, which causes it to fail inconsistently. This bug will be addressed in a coming pull request, but I reran that particular test after the full regression test to show that it is buggy and should not reflect the validity of the code requested to merge here.

@jjonkman @ghaymanNREL @michaelasprague Please let me know if you have any feedback regarding the updated naming that I've added here. I chose to avoid renaming every instance of "fast" to "openfast" in order to prevent any unnecessary bugs since modules and subroutine names contain "fast". Furthermore, I'd like to minimize introducing breaking changes for anyone using OpenFAST as a dll like @gantech.

[jjonkman]

The changes to NWTC_IO.f90/CheckArgs() are not universal. This routine is used not only by OpenFAST, but many other related programs including standalone drivers, TurbSim, etc.

The first problem is that "IF ( NumArg .EQ. 0 ) THEN" has been added to display the syntax. But this message should not be displayed if the program accepts a DefaultInputFile.

The second problem is that statements have been added regarding restart/checkpoint files, but these statements only apply to OpenFAST, not to other programs that may use this SUBROUTINE.

You may need to make a custom CheckArgs routine for OpenFAST (but this then should probably not be included in the NWTC Subroutine Library).

Everything else in this pull request is OK.

[rafmudaf]

@jjonkman I've reverted the portions of this pull request which you pointed out were incorrect. Rather than squeezing it in here, I'll leave issue #105 open for now. Please review again and let me know if you find anything else. And thanks for the feedback.

[jjonkman]

Why were lines 2659-2661 removed from NWTC_IO.f90?

The other changes look fine with me.

[rafmudaf]

@jjonkman that was a mistake, thank you for catching that. I've added those lines back in the latest commit.

[jjonkman]

Thanks for addressing my comments.

[michaelasprague]

This looks good.
