fix: lib/Parser.py: syntax_err(): error message: lightened the shade of gray so the boundary between the strings before and after the error would be clearer

moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).

Parser.py: Renamed SyntaxException to SyntaxError because it's an unexpected condition that should exit the program, a.k.a. an error

lib/*.py: Removed svn:executable property to turn execute bit off

Parser.py: Renamed _syntax_err() to syntax_err() to make it a public method

Parser.py: In syntax errors, only print <END> at end of string if error was at end of string

Moved everything in scripts to root. inputs_Makefile: Don't run "all" when installing.

Added faded beginning of string in Parser syntax errors

Refactored xpath.parse() to use a nested function instead of a class extending Parser

Fixed xml_xpath.get() last_only optimization to handle attrs correctly. Turned off stack traces for errors intended for the user to see.

Changed mappings to place prefix common to all XPaths in the column header

Moved Python modules to shared lib folder

data2xml: Added syntax for split paths, which map to multiple leaves

Added BIEN 3 scripts
