Attributes of html tags are converted to lowercase

[liayn]

We are using custom tags inside our mail templates. Running them through inky makes all attributes lowercase, which breaks other transformers down the compile pipeline as those are case sensitive.

As mentioned in #18 self-closing tags are also converted to empty tags.

<f:uid.page pageUid="123" />

gets

<f:uid.page pageuid="123"></f:uid.page>

but should be preserved.

I'm using version 1.3.7 currently.

I could solve this by setting this configuration:

.pipe(inky({
    cheerio: {
        xmlMode: true,
        lowerCaseAttributeNames: false
    }
}))
