Support/bypass for "import" and "from" keywords in the processing of description.ext

[mrCurry90]

This may be on the todo-pile already but raising it so it isn't missed for future versions.

The import call for description.ext
import RscCredits from RscTitles;
will result in an error

Expected "(", "=", "[]", comment, end of line, or whitespace but "R" found.

I guess since they are fairly new "import" and "from" are not being properly recognized.

I can see it being tricky to get it working proper without the full config reference to pull from but accepting the line as valid is a must since the error invalidates the parsing of the description.ext including CfgFunctions and all the problems that entails.
