Python-like localization support

[WPMGPRoSToTeMa]

Not really python-like, but inspired by it and by #18 of course.

First of all instead of capsing, like DID_DMG_HITS, we can use some default translation text (e.g. english text).
Secondly instead of %L we can use function style: L(player, "He did {damage:d} damage to you with {hits:d} hit(s)\nand still has {health:d}hp and {armor:d}ap.")

This simplifies localization process of plugin that doesn't support it. Look:

Format("He did {damage:d} damage to you with {hits:d} hit(s)\nand still has {health:d}hp and {armor:d}ap."
  , FmtArg("damage", damage)
  , FmtArg("hits", hits)
  , FmtArg("health", player.Health)
  , FmtArg("armor", player.Armor)
);

Becomes:

Format(L(player, "He did {damage:d} damage to you with {hits:d} hit(s)\nand still has {health:d}hp and {armor:d}ap.")
  , FmtArg("damage", damage)
  , FmtArg("hits", hits)
  , FmtArg("health", player.Health)
  , FmtArg("armor", player.Armor)
);

Just adding L(player, and )!

TODO:

• Plurals
• SetLanguageContext(player); to remove repetitive player's index in L for localized arguments or using last passed player's index if it isn't passed
• Translation file auto-creation, on runtime or maybe some source code analyze tool
• FMTARG macro that will expand FMTARG(var) to FmtArg("var", var)
• Something that i forgot or don't know about python-like localization
