Sqlean.py

This release brings the `crypto` extension. It provides secure hash and message digest functions like MD5 and SHA1.

This release brings the `text` extension. It provides `reverse()` and `split_part()` functions.

This release brings no new extensions. All the existing extensions are renamed:


sqlite3-json1 → json1
sqlite3-math → math
sqlite3-re → re
sqlite3-stats → stats
sqlite3-unicode → unicode
sqlite3-vsv → vsv

This release brings the `json1` extension. Usually, SQLite is compiled with JSON support, but in case yours is not, here is the separate extension.
