Including Sahi script globally

Sahi automatically includes userdata/scripts/global_include.sah file into every script/scenario that is run.

Default implementation of callback functions are available in this file.

global_include.sah must always be present at the root of scripts folder. If you have manually configured more than one scripts folder, the global_include.sah from the respective root folders will be considered.

In case a script root folder doesn't have global_include.sah file, user will see an error on console reporting the same.
