Failed to compile template: constant string too long

Steps to reproduce:

• a long file in tag/something.jte
• include in another jte file with @tag.something()
• render

Long templates should be somehow split up to stay under the Java length limit.

@casid This isn’t about methods or class files being too long, but rather the constant string size limit of Java, which is 65535 bytes, which is quite low for larger templates that don’t contain variables.

I’ve implemented a fix in #26 and classified this as a bug rather than an enhancement.

Alright, will do that. Good luck and let me know if you run into any problems with this approach.
