DEMObject and IOHandler have been modified so that the DEMObject is more or less intelligently updated while retaining the possibility to provide an optional argument turning it off (constructors which fill the DEMObject with real data by default now update the slope/curvatures/normals except if giving as a last argument *false*).

The first code for using the proj4 library for coordinates conversion has been writen in MapProj. It is still disabled by default since it suffers (at least) from a parsing bug: the coordinates argument is truncated when going through cfg.getValue() and therefore not valid (at least my checks work!).

A missplaced define (for PI) has been moved in IOUtils.

LegacyIO popc code has been cleaned up, removing the timers (that are not portable and thus a problem for WIN32 systems).

A typo in an error message has been fixed in Grid2DObject. A few unnecessary (ie: ugly) white spaces removed at some places (A3DIO.cc, etc)
