This allows the build of fxruby on MSYS2.

within the file.

This fixes build without fxscintilla when run per 'rake compile'

Thanks @Harvey-H for the so simple solution.

Fixes #38 and fixes #30

This requires the use of rake tasks to build the gem or before 'gem build'

On the other hand, it makes sure, that all generated files are included in the gem.

Some rubies of the travis-ci installation have bundler-1.13 and there is no real need for 1.14.

Update release date, tag with annotation, push to git and push all gem versions with a single 'rake release'

Unfortunately it doesn't compile, due to undefined methods.

This is necessary for RubyInstaller versions based on MSYS1 (Ruby < 2.4).

RubyInstaller comes bundled with zlib-1.2.7. Since the zlib1.dll is stored in the
same directory as ruby.exe, it is preferred in the Windows DLL load order.
The zlib1.dll that is bundled with fxruby is not loaded at runtime.

If we build fxruby with a newer zlib version, libpng will make use of the new
function inflateValidate() introduced in zlib-1.2.8, which results in a DLL
load error at runtime. We avoid this by sticking at zlib-1.2.7.

Disable rbx-3 for now, because it's too slow.

Output Xorg logs only in case of failure

Ubuntu doesn't provide the symlink /usr/lib/libfxscintilla.so
but only /usr/lib/libfxscintilla.so.19 .
Therefore we link against libfxscintilla.so.19 if -lfxscintilla
can not be resolved.

"gem inst glu" fails because of missing opengl header files.
