various improvements

- use dig for resolving host names
- ascon.c: fix terminator parsing
- property callback: change property before callback
- logger.c:default for logger period must be the old value instead of 1
- add frappy type history writing
- increase max. logreader line length
- HIPNONE returns "null" with json protocol
- encode strings properly in formatNameValue
- fix memory leak in json2tcl
- scriptcontext: do not show debug messages when script starts with underscore or when the "send" property is empty
- scriptcontext: remove args for action timestamp
- scriptcontext: "que" function will replace an already queued action, e.g. for 'halt
