Also implement 'local' to declare/delete local procs
* Add tests/alias.test for testing alias, current, local
* proc now returns the name of the proc created
* Add helper 'function' to stdlib
Reimplement glob and case to use local procs
* This keeps these internal procs out of the global namespace

Improve the ability to rethrow errors
* Allow return to rethrow an error by accepting '-errorinfo stacktrace'
* Also, 'catch ... opts' now also stores opts(-errorinfo) on error
* Use these to provide better stack traces from 'case' and 'try'
* Implement 'return -level'
Make try/on/finally more Tcl 8.6 compatible
* With support for 'on' handlers and docs
Add support for catch options to try
* Otherwise it's hard to use try to catch signals
Improvements to signal handling
* catch -signal now sets a list of the handled signals as the result
* catch -signal won't execute the body at all if a handled signal is pending
* up to 64 (jim_wide) signals can now be handled
* if catch -signal is nested, the innermost catch will catch the error
* new 'signal catch' allows ignored/blocked signals to be examined and cleared.
* update docs on signal handling
exec should indicate which signal killed the child
