Add a first-class installer

[RoystonS]

Software version

0.8.0

Problem

Some users are unpacking the zip, installing the software, and then not realising that they need to keep the unpacked zip file. If we move to a real installer instead of a zip, we can copy the BBL files to a separate location safe from zip-deletion.

Suggested solution

Use an InnoSetup installer.

What alternatives are there?

We could use NSIS or WiX. InnoSetup looks straightforward, although it doesn't provide an easy way to customise error messages with links (e.g. our 'report a problem with my exe.xml' link.)

See also #42 and #43, which this enables.
