* Fixed crash with hidden files
added "-force" parameter on "Get-Item" cmdlet. this is needed to get file info if the file is "hidden"
without this option modules like win_file, win_template, win_copy crashes on hidden files. this is because with "test-path" it sees that the file exists, but "get-item" can't get the file info.
for more information on "-force option": https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/get-item
* Add changelog and integration tests
* fix tests for older Windows versions
This change corrects problems reported by the `yamllint` linter.
Since key duplication problems were removed in 4d48711, this commit
mainly fixes trailing spaces and extra empty lines at beginning/end of
files.
