Redesign/translations

[Adriano-7]

Closes #1461

Some notes:

• This PR fixes the translation of courses and course_units
• The calendar and the schedule links break when the page is /en, that's why i use the languageSensitive condition
• The course unit sheet is still in portuguese eventhough the link is /en because the link we're using returns the info in portuguese
• There's a problem with the abbreviation of finished courses (see the TODO). LEIC it appears as BICE

The "BEIC" problem is not from here, should we fix it here? I don't think the goal now, we can live with that and fix later, my opinion

[Adriano-7]

The BEIC problem happens because the way we're getting the accronym is through regex. I don't personally think is a big deal, the way to solve this would be through an api or somehow changing the fetcher to give us that info

Exactly, the fix seems complex, so ignore it that for now
