- Installed a new 'alarm' method to centralize motion kills across alarm or reset events. Right now, this is controlled by system abort and hard limits. But, in the future, a g-code parser error may call this too as a safety feature. - Re(re)organized status messages to just print all errors, regardless from where it was called. This centralizes them into one place. - Misc messages method installed for any user feedback that is not a confirmation or error. Mainly so that there is a place to perform warnings and such. - New stuff installed and still made the flash size smaller by saving flash space from clearing out repeated '\r\n' pgmstrings. - Fixed a bug where hard limits message would print everytime a system abort was sent.
