localStorage key problem with two applications on the same domain

[nerezo]

Hi,

I am using server for my two web application internally (with IP Address). These two application uses same localStorage key (ngIdle.expiry) and override each others' expire times.

It would be great if a custom key name could be passed to IdleProvider.

Thanks.
