Support for pt-PT (Portuguese language, Portugal country "variation")

[HelderMagalhaes]

This is part 1 of PR, including string resources for translation of shapes and colors

To whoever doesn't want to wait for next release or manually build the project:

1. Within your BabySmash directory (or next to BabySmash.exe if you're using the single file archive), create a Resources\Strings (note: two folders, nested)
2. Download pt-PT.json (included in this PR) inside Strings folder

A related glitch was identified, in PlaySound, where the reading is hard-coded to <color> <shape> order; in Portuguese, that will by default be the reverse <shape> <color>; guessing that a parameter stating the order will be enough, possibly as part of string resources — Question:
Is there any known language that is dynamic regarding the shape-color ordering?
A follow-up might be added to this PR ("part 2") or as separate PR if this is reviewed/merged in the meantime.

Not a native speaker, but syntax looks good to me, and those feel right.

But yes on the glitch, ideally, assuming we're using e.g. ICU message syntax, we'd add a string whose template is like {shape} {color} or change to {color} {shape} for some language/locale and pass those in to the resource retrieval instead of hard-coded string concatenation. (Then per your concern, if any language did need to change the order dynamically they'd do so with a more complex selector in the ICU message template, so even though that feels very unlikely, it is still covered.)
