Add "Palatino Linotype" fonts. CORE-16272 - Add "Palatino Linotype", "Palatino Linotype Bold", "Palatino Linotype Bold Italic" and "Palatino Linotype Italic" fonts by duplicating "DejaVu Serif" fonts and renaming them. - Delete some "Palatino Linotype" font substitutes. - Add LICENSE file. I made these font files by using FontForge. Their family name is "Palatino Linotype". Their display names are "Palatino Linotype", "Palatino Linotype Bold", "Palatino Linotype Bold Italic" and "Palatino Linotype Italic". Their font filenames are pala.ttf, palab.ttf, palabi.ttf and palai.ttf. The Underline Positions are hacked by adding an integer value for workaround of FontForge's bug.
