[IMP] invoice, sale, purchase: template update

Templates used to send invoice / quotation / PO by email are cleaned. Custom
style is removed. Content is simplified.

For sale, only one template is kept through the various addons. Previously to
this commit there are 3 templates: standard, portal and online quote. Those
template are similar except the link to get the sale order. Now the base template
contains some logic that should be sufficient to cover all cases. This breaks
the modular approach but is easier to use for users. As templates are still mako
it is not possible to use inheritance. So having a base template knowing some bits
of overriding modules is necessary if we want to avoid having the same template
duplicated.
