This adds 4 tests for unreachable code and 1 future test. It also fixes
test.bat so that it exits with an error if the tests fail, and ensures
that tests are run by fixing the parent Makefile.

Fixes #355.
Fixes #1710.

This is structured as a feature so it is tested as such, but was part of
the set of fixes scheduled for 15.0 beta. Any rule in a group that
Keyman Developer assesses as 'unreachable' will receive a hint message.

The current rule match is fairly simplistic -- it only does an exact
comparison -- so duplication which is indirect, through `any(store)`
references in the context would still result in unreachable rules that
are not picked up.

chore(web): remove unused `selectLayer` parameter

fix(common): wordbreakers package.json main field

fix(android/engine): Clear WebView cache on package install

Fixes #6258.

While this was done in code as a global override, probably following
Apple stylistic changes, it is better to leave this to the keyboard
developer to decide on.

auto: increment beta version to 15.0.224

fix(web): ios popup positioning and style

fix(windows): make long menus scroll in Configuration

fix(mac): invalid keyboard breaks configuration 🍒

auto: increment beta version to 15.0.223

chore(common): Update Hausa strings

fix(windows): put correct HK_ALT flag for modifier

auto: increment beta version to 15.0.222

Fixes #6098.

If the list of languages is too long to fit, the menu now dynamically
adds a scroll bar.

As a bonus:
* The language names are sorted (non-Latin scripts at bottom for now)
* `nmake install` works again (in kmshell, presence of `install` folder
  was confusing it)

Fixes #4877.

If a keyboard is invalid for any reason (missing, wrong version),
then it would not appear in Configuration, which would break the
row indexing, causing crashes.

Cherry-picked from stable-14.0 branch.

fix(common): report more log detail in increment-version

fix(developer): structure sizes for kmcomp x64

Relates to #6391.

Adds some logging so we may be able to find out why we are getting
strange results for some PRs.
