[IMP] ir.translation: `module` field is useful for admin/debugging
[FIX] tools: mail: fixed shortening of html content.

Fixed length computation of text in html nodes: multiples successive
whitespaces are considered as one whitespaces; better truncate position
when adding a read more link; now always protect words (placed after
the first word that exceeds the shorten position); pre nodes are preserved
about whitespaces; when the read more link should go into a quote, it instead
goes at the end of the first parent node not being quoted instead of at
a wrong position.

Added tests for shorten position.
[IMP] tools: mail: added a protection in a string.find, could have a None argument

[MERGE] [FIX] tools: mail: fixed shortening of html content.

Misc :
- removed an unnecessary loop by merging two root.iter() that do not interfere
- changed occurrences of getiterator to iter, because getiterator is deprecated
- nodes are cleaned after processing, removing all attributes used to tag nodes
- fixed a bug about cleaning span containing only whitespaces not always cleaned

Added tests for shorten position.
