STM8 eForth 2.2.24.pre1 allows creating new board variants in downstream projects.

• the release archives contain source files and scripts for building a board configuration
• the Makefile is now more modular so that application projects can have custom Forth binaries
• the dictionary can be tailored more easily, e.g. for creating temporary dictionary entries for headerless core code

On the application side I'm still experimenting (e.g. in the STM8 eForth Modbus project).
