Java MessageFormat test

Infinitode 2 uses localization features of LibGDX but is also able to include strings into other strings with [@other_string_alias] and icon textures with <@texture-name>
Things it can't do:

• Format values according to the gender
• Country-specific number formating - all numbers use . as a decimal separator (because programming languages do that) and , as a thousands separator for readability (space is not used because it may lead to unwanted line breaks)
• Turn strings into upper / lower case or switch the case of individual letters

Tags explained:

• <@texture-name> - will be replaced with a small texture of the same name.
• [#RRGGBB] or [COLOR] - switches color of the text, see LibGDX's Color Markup Language (not a language actually, just a type of a tag).
• [@other_string_alias] - will be replaced with a string which has the alias specified. The included string is already translated into the same language.
• {0} or {1} or {0,number} etc. - are kind of a variables that will be replaced by the game. Explained here and there, but I'll try to make a cheat sheet which is easier to understand (find it below)

Each format tag is encapsulated into {} and the first thing inside of it is a digit from 0 to 9, which is basically a name of a variable (actually it is called an index of an argument but whatever).
For example, if we take a string "Tower deals {0} damage and costs {1} coins", the game will replace {0} with some damage number and {1} with the cost of the tower. If we swap those tags, the resulting string will no longer make a sense, so it is important to pay attention to what each variable means.
Note: variable {0} is used in the list below but it can be anything like {1}/{4}... too.

• {0} - inserts value as-is, the most common tag you'll find
• {0,number} / {0,number,integer} etc. - inserts value as a number, and you should only use such type of tags only if they exist in the original (English) pattern.
• {0,date,...} / {0,time,...} - while MessageFormat allows this, date and time tags are never used by the game in a form suitable for this type of a tag. Just avoid and forget them.
• {0,choice,...} - allows to insert some value depending on the numeric value of the variable - the most common use case is handling of plurals. It can be used to insert the variable itself or any custom text you specify - basically it is a simple "if" statement.
  Such tags always start with {0,choice, and then goes the list of "conditions", separated by the | symbol. Conditions can be specified like this:
• 1#one - if # is used, the variable will be compared to the left part (1 in this case) and only if it matches, the right part will be printed (one).
• 1<many - in this case, < means that condition requires the variable to be greater than 1, which will insert the right part (many) for 2,3,4... and anything larger than that.
• It does not work with >, all conditions must be specified from small to large.
• 2<{0} items - you can also insert format tags into the right part of conditions to print actual variables there.
Some examples:
• {0,choice,1#One apple|2#Two apples|2<Three or more apples}
• {0,choice,1#One apple|2#Two apples|2<{0} apples}
• {0,choice,1#One apple|1<Few apples|5<Many apples|100<Shitload of apples}
