Added text option so you can have numbered/lettered markers

[jlyon]

I wanted to create numbered and lettered markers rather than using fontawesome icons. This fork adds support for a text option that you can use instead of icon when calling L.AwesomeMarkers.icon. It also adds a textFormat option. If textFormat = 'letter', a number is converted to a letter and displayed in the marker (0=A, 27=AA, etc).

Example usage:

num = 1;
var marker = L.marker([item.Latitude, item.Longitude], {
icon: L.AwesomeMarkers.icon({
text: num,
textFormat: 'letter',
color: 'blue'
}),
});

// The letter used in the marker (B)
console.log(marker.options.icon.num2letter(num));

2021 and I would like to use such a feature as well. This library is great when you are building a Leaflet map visualization and need some custom markers. But I prefer the solution from #54 since it is more general (having an HTML field where you can put any html element instead of using a number to represent a character)
