proper env modifiers support

This implements proper modifier support in the env file using this new fork of the godotenv library. The modifier implementation is quite basic for but can be improved later if needed. See this commit for the actual implementation.

Because we are now using proper modifer parsing, it does not affect the parsing of value, so this is possible again:
```
MY_VAR="#foo"
```
Closes coop-cloud/organising#535
