* release-1.4.2:
  Bumping version to 1.4.2
  Updated the changelog for new features.
Add support for struct with list param shorthand

This was already supported within a list via
`list-structure(list-scalar, scalar)` but not in the non-list form of
`structure(list-scalar, scalar)`. This commit adds support and refactors
the code to reuse as much as possible between the two.
Update changelog
Merge branch 'struct-list-scalar' into develop. Fixes #882.
Added support for warning about and skipping files.

Files that do not exist or user does not have read access to
are skipped and users are warned that the file is skipped.
Enabled skipping and warning special files.

Files include character special devices, block special devices,
FIFO, and sockets.
Added Windows compatibility to warning about files.
