Add include flags for out-of-source build

Windows: Fix erroneous assignment statement

At least the compiler shows it as warning, from c7e26c35

Added some ideas to TODO.

gwenbuild: Check for "required" flag when checking dependencies.

gwenbuild: Decreased verbosity.

gwenbuild: Added template for convenience libraries.

gwenbuild: Accept "<data>" also inside "<project>".

gwenbuild: Fixed targt type staticLib.

Use a small helper script to create a non-flat ar lib.

gwenbuild: Fixed linking against internal static libs.

gwenbuild: More work on static libs.

Need to rebuild installable static libs because "ar Trc" creates flat
archives which only refer to included subfolders. We need to unpack and
repack such an archive for exports.

gwenbuild: Read GenericBuilders only once. Add "--static" arg for setup.

gwenbuild: Write context to file.

Will be used later to show some infos like defines used in folders etc.

text: Improved error message.

gwenbuild: Allow for "<extradist>" also inside <project>.

This allows to distribute README etc in the root folder where there is not
yet a target defined.

gwenbuild: Added command to generate a package tarball.

Creates a folder and copies files markes as "DIST" into it.
Next step will be to create the tarball from it and delete the dist folder.

gwenbuild: Add 0BUILD files to project file list.

Released 5.7.0beta.

gwenbuild: Also use ldflags. Use cflags/ldflags in tryCompile/tryLink.

gwenbuild: More tweaking of builder definitions.

Crosscompiling for Windows works now using mingw.

gwenbuild: Create different builders for different target systems.

Cross-compiling for Windows on Linux now creates binaries.

gwenbuild: Updated README.

gwenbuild: Use existing build command list instead of creating an returning new ones.

Also allow to differentiate between error adding dependencies and simply
empty dependency list (e.g. when requesting to build a file which is a
non-generated source file).

gwenbuild: Fixed dependency tracking.

PATH: Fixed some bugs in GWEN_Path_GetPathBetween().

gwenbuild: Improved <BuildFiles> code.

Can now also select matching files from the project file list. This will
be needed for gettext-related commands.
