[PATCH] fixes r163 to work with ragel 6.1, java, and jruby 1.1

[stepheneb]

Applied the updates to the ragel code for 6.1 to hpricot_scan.java.rl.

Updated method to acces IRubyObject object:

new IRubyObject[]{runtime.newSymbol("buffer_size")}

becomes:

runtime.getCurrentContext(),new IRubyObject[]{runtime.newSymbol("buffer_size")}

The include statements in the main ragel code didn't work with paths starting with ext/ so I made them into relative path references which did work.

Updates to the Rakefile to support easy compilation of the C ragel source code using different ragel compilation strategies. This is the default setting:

DEFAULT_RAGEL_C_CODE_GENERATION = "really_fast goto_driven"

which is -G2

The result is no test failures in C and only one in Java: test_latin1_entities.
