All URL is case-sensitive within the applause-button

[LazyRen]

IMHO, some part must not be taken as case-sensitve.

I just noticed this while playing around with #33.

I have reconfigured my blog setting to use lowercase for the hostname. (e.g. LazyRen.github.io/post-link -> lazyren.github.io/post-link)
But unfortunatelly, this erased all previously stored clap-count...

That's a fair comment, and should be easy to remedy. The fix would need to be done over in applause-button-server.

@LazyRen Would you mind adding an issue over there? Feel free to link back to this one.
