Subject: [PATCH] [IMP] release: add version number on App

Before this commit, the version number was added by the rollup
configuration script. It worked, but it meant that there was no robust
way to access the version number in many case. For example, what if I
have a page with two different version of owl? Or what if one of them
uses the ESM module system, and does not export owl as a global object?

This is not really a big deal, but accessing the version number is
useful for tooling purpose, so this commit makes it possible to read the
version number on each individual App, as a static property.
