#34 109: Import is case-insensitive

[Jukka Laurila]

TestFailed: import of RAnDoM should have failed (case
mismatch)

A very minor nitpick, but the Python specification
dictates that module names should be case-sensitive
when importing even on case-insensitive filesystems (if
possible).

A Symbian-specific implementation of case_ok() in
"Python\import.c" would be needed to solve this.
