Create java_snippet.JSON-tmLanguage

This JSON file allows users to use multiple syntax in one file in Sublime Text - a feature not inherently present. 
In this particular case, the user can enter java code blocks into a text file and the respective syntax (color coding in sublime) will be displayed depending on the start & end sequence defined. 

Layout example:
...
Plain text (Syntax: Plain text)
...
*{ // Begin sequence
Java code (Syntax: Java)
} // End sequence
...
(Syntax: Plain text)
...

This allows for a better UI especially while inserting code snippets/blocks in a plain text file.
