Attributes with periods not supported

[trevorade]

Angular supports the following:

<div [class.light]="this.booleanProperty" another-really-long-attribute-to-force-wrapping="this.yoYo"></div>

HTfloML formats this as:

<div
    [class
    light]="this.booleanProperty"
    another-really-long-attribute-to-force-wrapping="this.yoYo"
></div>

Without the long attribute, it gets rendered as:

<div [class light]="this.booleanProperty"></div>
