Added function DetectFontsAspects to Font_FontMgr class. This function uses workaround from OpenGl_FontMgr with FreeType for detecting font aspect. Removed font name parsing from Font_FontMgr::InitFontDataBase(). Now the font name and font style we get through the FreeType. Fixed Unix part of Font_FontMgr::InitFontDataBase() method. Font name and font style now detected through the FreeType. Remarks fix. Added recursive default font directories scanning . Fixed adding fonts folders recursively from configuration files. Moved fonts aliases map from OpenGl_Display_1 to Font_FontMgr. Moved fonts name definition from Graphic3d_NameOfFont.hxx to Font_NameOfFont.hxx. Added new methods to Font_FontMgr: GetAvailableFontsNames, GetFont and FindFont. Modified Font_SystemFont creation from XLFD. Added method IsEqual to Font_SystemFont. Modified methods OpenGl_Display::FindFont, OpenGl_FontMgr::request_font in accordance to the new functionality of the Font_FontMgr. OpenGl_FontMgr now stores only generated fonts instead of duplication of available fonts list. Removed method OpenGl_FontMgr::requestFontList. Its function now performs Font_FontMgr::GetAvailableFontsNames. Documentation was fixed Adjusting testing cases for current state of OCCT
