[i18n] Extract first few strings to resource bundle

[Pr0methean]

This extracts the localizable strings in GlowServer, lines 1-887, into a resource bundle. The rest can be done in a similar manner. Should a naming convention be established for the string keys first?

For one, I think there should be a prefix distinction between console output and in-game messages/strings.

e.g. console.info.something-something and game.something-else

Log levels should be prefixed too if the message is strictly related to that level, e.g. warning vs. info.

Also, periods should be there to split prefixes/groups of similar messages, while dashes should be used for multiple words. For example:

console.info.some-feature.enabled=Some feature is enabled.
console.info.some-feature.disabled=Some feature is disabled.

I think we should avoid the use of (conjugated) verbs and use more general terms, e.g. console.warning.proxy-enabled-online-server instead of proxy.support.is.enabled.but.online.mode.is.enabled

@momothereal How do these new message names look?
