Adding a computer reloads the list view

[fiveseven808]

When adding a new computer view the interface, the entire list view is reloaded fresh.

The side effect of this causes any machine that has not been responding (i.e. in the dead pile) to get a new "last seen" time, which may throw off calculations and such... if you were banking on a machine being dead for X amount of time for whatever reason...

Don't plan on fixing it for now, but going to note it just in case I feel like fixing it in the future.
