Use ILIKE/LIKE + UNION in Project.search
This chance is broken up in two steps: 1. Use ILIKE on PostgreSQL and LIKE on MySQL, instead of using "WHERE lower(x) LIKE lower(y)" as ILIKE is significantly faster than using lower(). In many cases the use of lower() will force a slow sequence scan. 2. Instead of using 1 query that searches both projects and namespaces using a JOIN we're using 2 separate queries that are UNION'd together. Using a JOIN would force a slow sequence scan, using a UNION avoids this. This method now uses Arel as Arel automatically uses ILIKE on PostgreSQL and LIKE on MySQL, removing the need to handle this manually.
