core.clj: added iterator-seq and enumeration-seq, both mapping to clojure.lang.EnumeratorSeq

To core.clj, added cast, float-array, etc., floats, etc.

Updated *.txt documentation files in root directory.

Fixed prompt string in clojure.main. Make Clojure.Main the default project.

Got rid of unnecessary EOF Exception (that gets caught) in the LispReader

Added main.clj to load, added Clojure.Main project

Added set.cjl and zip.clj to the load

Added many more overloads to Numbers to get better resolution on numeric calls (reducing boxing). Added aset-inc, aset-long, etc. to core.clj.

Fixed Var bindings in REPL loop in SimpleConsole. Inlined call to RT.IsTrue in condition test in IfExpr (not clear if a speedup resulted)

Added loading of core_print

Modified parser to generate class names closer to JVM method; fixed reference to removed text reader in core.clj

Factored out one-char pushback from line-numbering in LineNumberingTextReader/PushbackTextReader and modified LispReader from lookahead (Peek) to pushback to match JVM and solve console problem.

Major changes, including AOT-compilation, load/compile, lib loading (needs more testing), minor fixes.
