Starting with gsl (2.0+dfsg-1) the libgsl0-dev package has been renamed
to libgsl-dev, and libgsl0-dev is provided by libgsl-dev for transition
purposes.
libgsl-dev is likely to stop providing libgsl0-dev in the future. To
remain compatible with both GSL 1.x and 2.0 packaging libgsl-dev is now
the preferred (build) dependency, when it's not available libgsl0-dev will
be used instead.
The desktop-file-valide utility reported the following issues:
```
debian/qbrowser.desktop: hint: value "Qt;Education;Science;Geography;" for key "Categories" in group "Desktop Entry" contains more than one main category; application might appear more than once in the application menu
debian/qbrowser.desktop: error: value "map;globe;postgis;wms;wfs;ogc;osgeo" for locale string list key "Keywords" in group "Desktop Entry" does not have a semicolon (';') as trailing character
debian/qgis.desktop: hint: value "Qt;Education;Science;Geography;" for key "Categories" in group "Desktop Entry" contains more than one main category; application might appear more than once in the application menu
debian/qgis.desktop: error: value "map;globe;postgis;wms;wfs;ogc;osgeo" for locale string list key "Keywords" in group "Desktop Entry" does not have a semicolon (';') as trailing character
```
Only the Keywords syntax error is addressed, the Categories hint is left as-is.
The menu files are no longer required for the Debian packages since
[CTTE #741573 Debian Menu System](https://lists.debian.org/debian-devel-announce/2015/09/msg00000.html)
which advised:
> 2. In addition to those changes, the Technical Committee resolves that
> packages providing a .desktop file shall not also provide a menu
> file for the same application.
* fix build on windows
* fix grass build on precise (using cmake <2.8.8, ie. without INCLUDE_DIRECTORIES target property)
* support desktop & browser shortcut for GRASS 6/7 in OSGeo4W nightly build
* save block inserts in separate shape instead of expanding it
once at the first insertion (also removes GPL-2 only code)
* update dxflib to 3.7.5 (usable under GPL-2+)
