Replace Localization Tables with Fluent

[iamteapot422]

Summary

Fluent will allow us to properly apply grammar rules, which we would otherwise need to code in C# every time. We might be able to handle the grammar in the English language, but other languages with more complex rules for word forms would have a hard time. We can also use Fluent to store status texts and perform fancy formatting.

Examples

en-US.ftl

coins =
    { $count ->
        [one] { $count } coin
       *[other] { $count } coins
    }

C#

loc.Get("coins", ("count", 1));
loc.Get("coins", ("count", 5));

Output

1 coin
5 coins

en-US.ftl

player-joined =
    { $gender ->
        [male] He joined the game.
        [female] She joined the game.
       *[other] They joined the game.
    }

C# Usage
loc.Get("player-joined", ("gender", "female"));

Output
She joined the game.

en-US.ftl

quest-status =
    { $completed ->
        [true] Quest Completed!
       *[false] Quest In Progress...
    }

C# Usage
loc.Get("quest-status", ("completed", true));

Output
Quest Completed!

en-US.ftl

start-button =
    .label = Start Game
    .tooltip = Begin a new adventure

C# Usage

var message = bundle.GetMessage("start-button");
var tooltip = bundle.FormatPattern(message.Attributes["tooltip"]);

Output
Begin a new adventure

---

en-US.ftl
score = Score: { NUMBER($points) }

C#
loc.Get("score", ("points", 12345));

Output
Score: 12,345
