Release 1.1.0

This is a compatibility and feature release.  This release adds one new
feature, the ability to control the quote character used.  This allows you to
do things like:

```puppet
  ini_subsetting { '-Xms':
    ensure     => present,
    path       => '/some/config/file',
    section    => '',
    setting    => 'JAVA_ARGS',
    quote_char => '"',
    subsetting => '-Xms'
    value      => '256m',
  }
```

Which builds:

```
JAVA_ARGS="-Xmx256m -Xms256m"
```
