Major conflicts with other leaflet plugins

[danwild]

I'm not 100% on what is happening here, but when I simply import this plugin alongside other leaflet plugins, things break.

Here's a simple example trying to use Leaflet.glify along side another popular plugin, Leaflet.draw:

I've also encountered issues when using with leaflet-loading and leaflet-mouse-position.

It seems like there's something funny happening in the dependency tree, the plugins are conflicting somehow.

Potential solution - make leaflet a peer dependency

I noticed that leaflet is listed a direct dependency of this plugin rather than a peer, which sounds like a better fit for a "plugin package".

PR/example to follow.

Cheers,
Dan
