TULIP_INT_VERSION uses less digits in tulip5 than tulip4

[rgiot]

we cannot make conditional code for tulip4 or tulip5 because TULIP_INT_VERSION of tulip 5 is lower than TULIP_INT_VERSION of tulip 4

[rgiot]

For example we have to do

#if TULIP_INT_VERSION == 501
    tlp::node n;
    forEach(n, g->getNodes()){
#else
    for(tlp::node n:g->nodes()) {
#endif

instead of something like

#if TULIP_INT_VERSION >= 5000
    tlp::node n;
    forEach(n, g->getNodes()){
#else
    for(tlp::node n:g->nodes()) {
#endif
