Asset lists created for use by kiterunner use negative lookahead, which is not supported by kiterunner

[hlein]

The routes-small.json and routes-large.json asset files created for use by kiterunner include regexes that use negative lookahead, (?!...).

But the regex library used by kiterunner does not support negative lookahead, so when debugging is turned on one sees tons of errors when these are used.

I created an issue for kiterunner a few weeks ago but it has gotten no love, maybe this is a better place for assetnote/kiterunner#51
