add utility to strip localhost results from search rank file

[heckj]

expand the, or potentially add another, CLI tool with an additional command:

• stripping (the last)|(all) localhost stored searches from a .searchrank file

Turns out manually iterating through all the various pieces to see how it was doing was kind of a pain, and a CLI tool to do that would be SO much nicer.

It may well be that I'd like to re-capture for all local searches as well - so not just "get rid of", but also "add one for this search", just to make the iterative development a bit easier.

reset the model, so this is no longer relevant.
