importing a module given a path to the file

[Skaperen]

i still like to write config files in Python. so, i'd like to have some kind of support for that. it needs to have a way to be controlled for security in cases where the config or data it uses comes from untrusted sources like a web query. advantages include:

1. config settings can have relations between each other such as a number setting that is 3 times plus 72 more than another number setting or a string that is the same as part of another.

2. the ease of a multi-line string that triple-quoting has.

3. accessing information from the file system or other files to establish settings.

4. the ability to do calculations that ordinary config files cannot do.
