FontAwesome support for when htmlLabels=false

[JohnLBevan]

Font awesome characters are not shown; rather the code (e.g. fa:fa-server) appears, when htmllabels is set to false.
This has a knock on effect that the text no longer fits in the box.

With htmllabels set to true all works (though not in IE11; per #303).

---

Workaround:

Use the following code so we only set htmllabels to false when using IE:

var config = {
    startOnLoad: true,
    flowchart: {
        useMaxWidth: false,
        htmlLabels: (!IsIE()) //this line is key
    }
};
mermaid.initialize(config);

Related IsIE function would be something like this:

function IsIE() { //other functions are available: http://stackoverflow.com/questions/19999388/check-if-user-is-using-ie-with-jquery
    return (navigator.appName == 'Microsoft Internet Explorer' || navigator.userAgent.indexOf('MSIE') !== -1 || navigator.appVersion.indexOf('Trident/') > 0);
}
