#17 Missing description if const function

[Kai K.]

To handle const functions the transformations may append "_const" to the name of a function if it is declared with and without const modifier.

Steps to reproduce:
1. create a C++ class
2. add "void myfunction();"
3. add "void myfunction() const;"
4. document the functions
4. run "ant meta2java"
5. look at java class if the docs are copied
