Add Chinese UI support

[ahuiiiiiii]

Mirth is a very good software, but it does not support chinese UI, which has some problems for software implementation.

@yimengZJl is also a chinese user. Look for their posts on GitHub and the forums. The important issue for Chinese support is being able to replace the fonts in Mirth Connect.

Is Mirth Connect Admin even internationalized? I can see some evidence of internationalization (e.g. MirthRSyntaxTextArea.properties) but also evidence that it is not internationalized (e.g. Frame.java).

I think this is a really good opportunity for the Open Source community @twest-mirthconnect and @narupley to get involved. We would just need a little direction for how you'd like us to get started with wiring i18n into Mirth Connection Admin. For example, should each class have its own resource bundle or should there be one giant resource bundle with all strings (or something in between), and how should a piece of code get access to those resource bundles?

We can do all that grunt work while you guys build new features.

It isn't but I will bring it into conversation this week with the team and let you know.
