- Implemented tcl: prefix which allows to execute a command in Tcl directly

- Fixed a stack overrun bug in macro.c
- Fixed a killing bug in devser.c
- Added node writing with offset to nxscript.c
- Wrote a simulation driver for second generation HM's
- Readded devexec commands to  SICS
- Readded Hipadaba initialisation to SICS
- Fixed a bug in sinqhttprot.c which is triggered when a reconnect happens
  during a node based download of data.
