Hashell-0.15: CHANGELOG

	Changelog - Hashell (0.011a -> 0.013a)

   -- Part of the parsing is now done with Parsec. 
   Parsec will partially substitute the majority of the parsing tasks.
   -- Added a new exception handler for haskell expressions
   evaluation. This fixes a bug that aborted hashell.
   -- Added redirection of standard error.
   -- Fixed 'quit' built-in command bug.
   -- Added number identifiers to the redirections operators.
   -- Added pre-liminar support for environment variables.
   The support is contained into its own module.
   -- Changed (_yet_ again) the syntax for sub-process evaluation 
   from '<|proc|>' to '(-proc-)' (without the quotes).
   -- Type constraints for haskell expressions evaluations are now limited
   to the ':<s,p,n,u>' notation. Values:
   	's' String without newline.
	'p' Non-String with newline.
	'n' Non-String without newline.
	'u' String with newline.
   -- The 'execSplitToken' function has been re-written. It is now
   split into several smaller functions and with better exception handling
   support.
   -- Hashell will now automatically read the configuration file with name
   .hashell_config if it exists inside HOME.
   -- The comments format in the hashell configuration file has changed
   from '*' to '-'.
   -- The command composition feature was removed.
   -- Others smaller bugs have been fixed too.
