Run memcheck test on Travis SI

[mloskot]

CMake can automatically run memory check with valgrind.

In order to run memcheck on Travis CI, currently used commands need to be updated as follows:

sudo apt-get install -qq valgrind
cmake -DMEMORYCHECK_COMMAND:FILEPATH=/usr/bin/valgrind ..
ctest -T memcheck

Example output:

mloskot@brzuchol:~/dev/geos/_svn/trunk/_build$ ctest -T memcheck
   Site: brzuchol
   Build name: Linux-c++

100% tests passed, 0 tests failed out of 4

Memory checking results:

The long detailed valgrind output is sent to separate file (with timestamp'ed name):

Testing/Temporary/LastDynamicAnalysis_20130828-1256.log

Let me know if the memcheck should be enabled.
