Subject: [PATCH] Clean up LaTeX font handling (#4999)

The LaTeX font information are now centralized and outsourced. This removes a lot of hardcoding and duplication and makes it easier to support new LaTeX fonts.

+##########################################################################
+#
+# LaTeX fonts natively supported by LyX.
+#
+# Syntax:
+#
+# Font <name>
+#	GuiName            "<Gui Name>"
+#	Family             <rm|sf|tt>
+#	SwitchDefault      <0|1>
+#	Package            <LaTeX package to be loaded>
+#	Requires           <LaTeX package to test for>
+#	AltPackages        <alternative packages (comma-separated)>
+#	OT1Package         <alternative package specifically for OT1 encoding>
+#	CompletePackage    <alternative package for the complete family>
+#	OsfOption          <option for oldstyle figure support>
+#	ScOption           <option for true smallcaps support>
+#	OsfScOption        <option for combined osf and true smallcaps support>
+#	ScaleOption        <option for font scaling>
+# EndFont
+#
+#
+# NOTES:
+#
+# * Adding a new font results in a FILE FORMAT CHANGE. So if a new font
+#   is added for the LyX distribution, the according changes need to be
+#   done.
+# * "SwitchDefault 1" makes the font to be loaded by switching the default
+#   family to <name> (e.g., \renewcommand{\rmdefault}{cmr}), whereas
+#   Package <package> loads it via \usepackage{package}. Normally, only
+#   one of these options is used per font.
+# * If AltPackages are defined, LyX will try to load them in the defined
+#   order if the main package is not available. So
+#       Package          mathptmx
+#       AltPackages      mathptm,times
+#   will try to load mathptm if mathptmx is not available and then times
+#   if mathptm is not available either.
+# * If Requires is set, LyX will check for this. If not, it will check
+#   for Package and AltPackages.
+# * OT1Package will load the defined package instead of the default
+#   package if the font encoding is OT1. This is necessary since some
+#   newer packages for a font do not support this encoding.
+#   The value "none" tells LyX not to load a package in OT1 encoding.
+# * CompletePackage is a package that is loaded if the current font is
+#   selected as rm and both sf and tt are set to "default" (this allows
+#   f. ex. to load "bera" as opposed to "beraserif").
+# * OsfScOption overrides any OsfOption and ScOption if both features
+#   are selected.
+# * ScaleOption supports the placeholder $$val for the scale value.
