- launcher no longer knows about egg storage
- removed get_spider_list_from_eggifile() file and replaced by simpler
get_spider_list() which doesn't receive en egg file as argument
- changed "egg runner" name to just "runner" to reflect the fact that it
doesn't necesarilly run eggs (though it does in the default case)
--HG--
rename : scrapyd/eggrunner.py => scrapyd/runner.py
* added minimal web ui
* return unique id per job (spider scheduled)
* store one log per spider run (job) and rotate them, keeping the last N logs (where N is configurable through settings)
