jParsec 3.0

[Locke]

This upgrades the jParsec dependency to 3.0.

There are some major changes from 2.x (from https://github.com/jparsec/jparsec/releases/tag/3.0-rc1):

• Java 8 is required
• "Change package names from org.codehaus.jparsec to org.jparsec"
• "Adapt code to Java 8 features: Remove various FP-like utilities, use lambdas everywhere..."

I applied the renamed package in 6e51145, and later on in 3fd3972 I followed the deprecation warnings and made use of the new Java 8 API.

Note: I'm not using Eclipse so I haven't tested that part.

Just pushed some new commits:

• rebased onto master
• fix deprecation of .optional() without default value to use .optional(null)
• some code style improvements
• I noticed that in ParserTools.java a lot of methods have an unused name argument. I deprecated those methods and moved their implementation to the methods without the name argument to make clear hat the name argument is unused
• updated to jParsec 3.1
