Bugs, features and tests

source fails with zero length file
unknown can't be called recursively
*: This can be useful when using unknown to dynamically load code,
   which may in turn want to dynamically load code
*: Limit it to 50 recursions though
Allow string greater/less comparison
*: Comparing two strings for order did not work
Implement file join
*: It's not to hard and is handy when working with the current dir, ""
Don't omit [unknown] completely from stack trace
*: Since we lose valuable informtion, just omit the name
Fix return from case
Turn regexp patterns into real objects
*: Thus caching the compiled regexps
Allow error to rethrow an error
Replace bcopy() with more standard memcpy()
Fixes to parray, improve errorInfo
*: errorInfo takes an optional stack trace
Add tests for rethrowing errors via errorInfo
Fix ndelay
*: Was looking at wrong param
*: Also fix usage/help for aio.socket
Package should be able to call exit
*: Currently any return from a package is changed to JIM_ERR
Line counting is incorrect for backlash newline
