This brings a series of improvements to the mechanism in place to
convert the output html of mass mailing into html that is more compliant
with the main mail clients' requirements.
The biggest change is the automatic conversion of Bootstrap grids into
table structures. Currently all templates in `mass_mailing` are designed
with tables so they work in mailings as is. That has limitations though
as it makes it less easy to edit with snippets such as those used in the
website builder. This new automatic conversion from Bootstrap grid will
allow us to adapt the mailing and snippet templates and be more free
within `mass_mailing`.
Note: Because of the limited support of media queries in emails, this
doesn't support the mixing and matching of column options
(e.g., `"col-4 col-sm-6"` and `"col col-4"` aren't supported).
Other changes include:
- The conversion of Bootstrap cards to table structures
- The conversion of Bootstrap list-groups to table structures
- The conversion of snippets (.o_mail_snippet_general) and mailings
(.o_layout) into table structures
- The conversion of all rgb colors to hexadecimal
- The conversion of all "rem" sizes to "px"
- Various small corrections to the output styles
