.toml files do not support Windows path

[aardschok]

Issue

When adding application specific python paths for example we need to replace the "" with "/"

Motivation

The .toml files support relative paths with the format approach : {AVALON_CORE}
Extending the support to normalized path seems logic .

Proposal

Together with recreating the absolute convert the path to the OS normalized path.

# pseudo code
absolute_path =string.format(os.environ[**keys])
os_supported_path = os.path.normpath(absolute_path)

Sorry I missed this @aardschok, I'm sure you've moved on since then, but I think this is a solid idea.

I have moved in the meantime yes. Good to here you like the idea 👍
