How to automatically add revision number to version number

[GoogleCodeExporter]

Currently the version number is hard-coded in const.h and is updated manually. 
This is fine for major releases but may be not accurate for intermediate builds 
(bug fixes or new enhancements). The latter can be distributed among some users 
for testing purposes.

The idea is to somehow get the current revision number from the subversion 
during compilation and add it to version number, making it look like 
1.1a5.1034. However, further study is required to understand whether it is 
doable at all with acceptable complexity.

This solution adds the revision number to the output of 'adda -V', like "ADDA 
v.1.1 (r1234)". For other output (like shape files) the short version (like 
1.1) is kept to minimize unnecessary diffs.
