Autodetection of L.Icon.Default.imagePath, getScript() inclusion

The method used to auto detect the correct path to the default marker and shadow images causes problems under two circumstances:

1. The search regex /\/?leaflet[\-\._]?([\w\-\._]*)\.js\??/ also matches unintended similar files such as leafletFooBar.js, giving the markers the wrong relative path. Since only leaflet.js and leaflet-src.js need to be matched, /\/?leaflet(-src)?\.js\??/ might work instead.

2. The nature of the method being used (search the page for the correct script tag) defeats the use of getScript() to include leaflet.js from another file, as in this case the desired script tag is not present in the page.

L.Icon.Default.imagePath = 'path-to-your-leaflet-images-folder';
// your other Leaflet code

Same issue here after moving <leaflet-map> from the index file into a component (using Polymer here).

I had to set the path like this:

ready() {
    L.Icon.Default.imagePath = '../bower_components/leaflet/dist/images/'
}

And the map would display the icons again.
