... in cases of "TranslatableString" that are not really translated.
This makes it easier to scan the code for such unusual constructions of
TranslatableString, distinct from mere mentions of the TranslatableString type.
... Unnecessary because transitively included.
But each .cpp file still includes its own .h file near the top to ensure
that it compiles indenendently, even if it is reincluded transitively later.
... except Audacity.h
This forces us to make each header contain all forward declarations or nested
headers that it requires, rather than depend on context.
... except Audacity.h; and in no others.
Do so even if Experimental.h gets multiply included, as in both the .h and
.cpp files.
This makes it easier to do a text scan to be sure there are no unintended quiet
changes of meaning because of omission of Experimental.h when the flag is
an enabled one.
Also move inclusions of Experimental.h earlier.
Also don't require Experimental.h to be preceded by Audacity.h to define
EXPERIMENTAL_MIDI_OUT correctly.
... Some in wxT can be edited directly, some in _() are not really used now
so they can be edited directly, others require a post-translation substitution.
Not all links to libraries from Credits work with https: so update only those
that do.
... There are two in AboutDialog.cpp, but these strings aren't actually used.
There are two in InconsistencyException.cpp, which ought never to be seen by
users, but should be treated as high priority bugs if they are.
There is a very old one in Sequence.cpp, which was never internationalized and
was only written to the log and likewise ought to be eliminated from happening
in pre-release testing.
Therefore, though this is a minor breach of string freeze, it's only the second
one above that users might ever see, and then only if a serious bug escaped.

The welcome screen now has an extra prelude for Alphas, and as result no longer needs to force a version check onto our website. Users can still do that by clicking "check online".
I've also rearranged the version check code a little, so that there is better reuse. E.g. we can change the URL in just one place in the code.
