lcm-java generates invalid code when messages with fields named "interface" are used

[poolfeast-420]

The following LCM definition will create an invalid .java file. Because it uses the reserved "interface" keyword as a variable name.

struct Demo {
    byte interface;
}

Creates the following Java code:

/* LCM type definition class file
 * This file was automatically generated by lcm-gen
 * DO NOT MODIFY BY HAND!!!!
 */
