Add possibility to append to an existing variable

[franzlst]

For an .env script like

PATH=/my/path:${PATH}

the plugin should prepend the current PATH with /my/path. Thus, if PATH=/another/path, the environment should result in PATH=/my/path:/another/path. Currently, PATH ends up being /my/path:${PATH}

Proper support would required shell script interpreter invocation but maybe we can go with simplified support where only $NAME or ${NAME} is supported (as opposed to ${NAME:-default} and so on). Would it suit your use-case?

[franzlst]

Yes, that would be perfect. That would be the same behavior as in the "Environmental variables" that you can set manually in the PyCharm run configuration.

I'm going to add this as an optional feature using https://commons.apache.org/proper/commons-lang/javadocs/api-3.3.2/org/apache/commons/lang3/text/StrSubstitutor.html

Implemented, will be released soon.
