Global resources options

Often, all resources of one type (file, package, service etc.) in one manifest have few common options. Instead of writing many strings of repetitive code like this:

file { "foo":
    ensure => file,
    mode => 600
    # some other code
}

file { "bar":
    ensure => file,
    mode => 600
    # some other code
}

file { "some_file":
    ensure => file,
    mode => 600
    # some other code
}

better set common options for all resources of one type in current class:

File {
    mode => 600
}

NOTE: name of type begins with a capital letter
This will produce better readability and less unnecessary code.
