kOS: Scriptable Autopilot System

# v1.1.5.0 HotFix for nested function scope.

Built for KSP v1.3.1

This release is just to fix one bug introduced by v1.1.4.0
that was discovered post-release by the users, during the
Christmas-NewYears time. The fix was quick but release
was delayed for after the holidays.

### BREAKING CHANGES:

None that we know of. This change shouldn't even require
recompiling KSM files, presuming you had them recompiled
already for v1.1.4.0.

### BUG FIXES:

- The default scope for ``declare function`` when you say neither
``local`` nor ``global``, was always defaulting to ``global``
in the previous release (kOS 1.1.4.0), when it was supposed to be
context dependent. It was meant to be ``global`` only when the
function is at outermost file scope, but ``local`` when the
function is nested at any inner scope deeper than that. This is
now fixed, and this bug is the main reason for this hotfix release.

- The above bug also exposed a vulnerability in how kOS's own errors
(ones that are the dev's fault, not the user's fault) are dealt
with. If ReplaceLabels() (a final step of loading a script into memory,
that happens when you RUN a .ks or .ksm file) threw an exception,
then the user would see the same error message repeating forever,
and never get control of that kOS computer back again. (This
vulnerability was introduced when compiling was moved to its own
thread, for complex reasons, but only just discovered now because
this was the first time ReplaceLabels() had an exception since that
move had happened.) It is fixed now.
