Add message box when clicking "More" in AmiiDB results list

[Schokobecher]

This should close #241

• Added _L_APP_AMIIDB_MORE_MESSAGE in English and German
• Added message box handling to amiidb_scene_amiibo_search.c
• Rebuilt language files

Pressing [More...] leads the user to this screen:

Confirming leads them back to the search result scene.

To-do:
Translate _L_APP_AMIIDB_MORE_MESSAGE in other languages

Since this is both information and advice/instructions for action, why not use the [_L_KNOW] button here (which means “Got it”)?
Because there is essentially nothing to confirm in such a situation.

[Schokobecher]

Both strings convey the same meaning. You could argue that we can remove both, and just use OK in any instance where they are currently in use, and nobody would notice or care.

The user confirms (Confirm)/acknowledges(Got it) that he has seen

• That there is either an issue
• or something has to be done by the user to progress

[MayanKoyote]

In situations where the user can say 'I confirm', he can also say 'I do not confirm' in case he doesn't like it. In other words it's 'I cancel' or simply 'Cancel'.
In the case where the user does not have the power of choice (as in this search case), the user can only take note of it by saying 'Got it'. Just like in case of missing key-file.

[Schokobecher]

In which case the User can always say Ok and Cancel, just like in most programs. So the right thing would be to ditch both strings entirely and use only Ok across the board.

I vote for "OK"

[Schokobecher]

I changed it to _L_KNOW for know, since changing unrelated files doesn't really fit this PR's purpose.
