Fixed AR-435: Added system bootstrap and shutdown hooks for native executables

- See the RuntimeExecBeansTest-context.xml for examples of how to put these together
 - Shutdown hooks are executed on ApplicationContext shutdown or VM shutdown, whichever is first
Moved native executable error code detection into RuntimeExec class
 - This affects any existing RuntimeExecContentTransformers (e.g. TidyTransformer)
Made OS search use regular expressions
 - Command search order is: Exact name, First matching REGEX, *
 - Note that * is a special case for 'default'.  The REGEX equivalent is .*
