This way it's actually possible to use cmake-gui and build the library without building tests.

MinGW supports this API and adding libuuid to the Windows build is not
easy as this is part of the util-linux package which has lots of Linux
specific code.

This is tested via MXE based build for OpenSCAD.

- remove/update different outdated comments and points of contacts

- externally adds new function lib3mf_reader_getwarningutf8
- internally uses UTF8 strings for all warnings

* First working UTF8-implementation

* Remove unused code im xml-reader

* Remove plenty of unused 'GCC'-code

* Port VS unittests to gtest

* Make UTF8-changes and UnitTests compile on linux

* Fix MAC build

* Address some TODOs

* Remove broken COM-functionality

* Change some more interfaces to UTF8

* Remove unsused includes and NMR_COM_NATIVE flags

* Up the version number

* Remove ATL from examples

* Remove unused OPC-headers

* Make NMR_COM_NATIVE settable on the command line

* 32 bit builds need explicit cast when converting uint64 to size_t

* Negate offset when ZIP_SOURCE_SEEK from SEEK_END 

custom_zip_source_callback from the zip library where the cmd is ZIP_SOURCE_SEEK and whence is SEEK_END specifies a negative offset.  pImportStream takes an unsigned positive value to indicate the distance to seek back.  The value must be negated between the two APIs.

* Assume unsigned argument for seekFromEnd

The API for CImportStream and CExportStream only allows unsigned input.
This commit handles this consistently in all seekFromEnd-functions
and adds some exceptions in custom_zip_source_callback.

* Support zip seeking backward from the current position.

* Update version

* Speed up OSX-builds

By not auto-updating brew

* Comment Travis CI-configuration

For linux, osx
