Subject: [PATCH] added Pry::NAV_PROMPT and Pry::SIMPLE_PRINT to pry.rb

NAV_PROMPT shows you your current context along with all the previous contexts separated by a "/" a la shell-style; making it easier to navigate around. Also includes current index of _in_ and _out_ locals.

SIMPLE_PRINT is just a simple inspect style printer (a la IRB); it doesnt use coloration or pretty printing or paging and can die for weird input. But is likely slightly faster for large output

 * got rid of Pry#null_input? since all that was needed was eval_string.empty?
 * cd command now supports complex syntax: cd ../@y/y/../z
 * JRuby is no longer a 2nd class citizen, almost full JRuby support, passing 100% tests
+* added Pry::NAV_PROMPT (great new navigation prompt, per robgleeson) and Pry::SIMPLE_PRINT for simple (IRB-style) print output (just using inspect)

 * cat --ex (cats 5 lines above and below line in file where exception was raised)
