[Fix #1418] Avoid deprecation warning for hidden directories

Even the recommended pattern style would generate
"Warning: Deprecated pattern style" before this fix. Hidden
directories are not matched with the new style of matching,
but that's intentional. Hidden directories must be
explicitly added in Include parameters in order to be
inspected.
[Fix #1416] Handle begin/rescue/else/end in ElseAlignment

A spec example for correctly aligned else in begin/rescue/end
was missing, so a bug slipped through.

[Fix #1425] Find included files in a simpler way

Only look in the "base" configuration when finding the
target files, not in the configuration associated with
each file under consideration. This removes a feature
that has existed for a long time, but hopefully isn't
used by many people (the ability to put AllCops/
Include parameters in .rubocop.yml files in
subdirectories). We didn't cover the existing behavior
in specs, but the new behavior is covered.
