Issues with "import" function

[maplant]

Firstly, the file path given to import has to be a direct path. This should be modified (and this is really a very easy thing to do) to check for the $FACT_PATH environmental variable.
Secondly, if the loading of the module fails, I am 90% sure that if the module is attempted to be loaded again, returning a "cannot re-load module" error. This should be fixed.
