Message:

kmk_append: Extended it with an -i parameter that enables looking for --insert-variable=xxx and --inserv-command=xxx. This allows us to merge the kmk_builtin_append commands at the end of each compilation, which significantly (e.g. 1m4s -> 37s) speeds up builds on windows and its dead slow file system.
