* some extensions needed by libTextSuite

* example project for Delphi

- texture data alignment
    - sigsegv when rendering without anti aliasing,
    - do not stretch last line in justified block
* store all object references in text suite to free them all when context is destroyed
* added code pages to convert ansi to wide string

* cleaned up project directories (move examples to subdirectory, deleted old text suite sources, ...)
