Migrate from sqlite crate to rusqlite

Resolves #384

@Lonami, I tried this on my Windows 10 machine, and yeah, it was a little bit of pain, as it often is with Windows 🙂
I did manage to make it work though.
The error was as follows:

error: linking with `link.exe` failed: exit code: 1181
  |
  = note: ...
  = note: some arguments are omitted. use `--verbose` to show all linker arguments
  = note: LINK : fatal error LNK1181: cannot open input file 'sqlite3.lib'

See https://cmsd2.silvrback.com/rust-msvc for how to resolve it.

Basically It boils down to this:

• You'll need SQLite3 DLL/DEF files (downloaded, installed via Chocolatey, etc.)
• Use lib tool (Microsoft Library Manager) from MSVS to make sqlite3.lib:

  lib.exe /def:sqlite3.def /out:sqlite3.lib
  

• SQLITE3_LIB_DIR env var needs to point to folder containing sqlite3.lib
• sqlite3.dll needs to be on the library search path, easiest way is to add its folder to PATH

For binary crate, you could just use rusqlite feature bundled, but for library I don't think this is really an option. It can be done for dev configuration though.

Thanks for the change and instructions! I can just squash during merge so feel free to push as much as needed.

This is about what I had in mind. On my Win machine, tests now work without sqlite dll/def/lib shenanigans.
