Upated clickhouse: pushed to master

[audrism]

I added search on author/project/comment field

Is it possible to submit the query without entering start tim?

I'm not really sure. The way we've used it in the past was returning commits matching a pattern between a time frame, but I guess it would be possible to do it with it. They main problem would be that clickhouse returns so much information that the website wouldn't be able to handle it. We do limit what it can return to 50k so we could just keep that limit. I'll have to look into it to see if we can query without a timeframe
