[FIX] translate: allow common english 2 chars terms

Before, all isolated (between xml/html tags) two chars words coming from views were not translated (by choice).
But, for some words, allowing them is useful. For instance, the word 'or' located between two buttons.

[FIX] sale: rounded sales team invoiced gauge

The price_total field of the account invoice report is not rounded (it cannot be easily rounded, as this has to be done in the sql view)
In a multi currencies environment, this is possible that the price_total value has a lot of digits
We therefore round it manually, for the gauge of the sales team kanban view
