Image version now accept a string of digit separated by dots and extra char as
a qualifier (~ or +).

Example:
1.2.3.4~dev < 1.2.3.4 < 1.2.3.4+dev

Old repositories are still compatible thanks to sqlite type affinity
(https://www.sqlite.org/faq.html#q3

).

We use a package version comparison algorithm for image version comparison
inspired by Debian.

New pattern is: [repository/][image][:version] (image is now optional).
Allow to select images in repository without globbing: 'is list repository/'
now work as 'is list repository/*'.
Same for version, for example: 'is list :*dev' work as 'is list */*:*dev'.

For example, if you have the following scripts in an image:
lib/
   |- 01-foo.py  (module 'foo')
   |- 02-bar.py  (module 'bar')
module 'bar' (and subsequent) could import and use content from module 'foo'.
