Pre-built custom sql.js for sqliteviz (#62)
* Proof-of-concept pre-built custom sql.js * Rewrite Makefile as a couple of comprehensible Python scripts * Add link to a blog post about transitive closure in SQLite * Remove eval extension -- no much point as it only returns a string * Consistently use existing Path objects * Add basic tests scalar functions from extension-functions.c * Test presence of functions from the rest of built extensions * Use the same sqlite.com domain * Add a couple SQLite compile flags that may make it a bit faster * Add regexpi function test * Add node about regexpi and REGEXP operator * Workaround first build failure, rebuild lock file and minor fixes
