Font: Overhaul font asset discovery Previously, any font names requested by RGSS would be translated directly to filenames by lowercasing and replacing spaces with underscores (and finally doing some extension substitution). To make this whole thing work smoother as well as get closer to how font discovery is done in VX, we now scan the "Fonts/" folder at startup and index all present font assets by their family name; now, if an "Open Sans" font is present in "Fonts/", it will be used regardless of filename. Font assets with "Regular" style are preferred, but in their absence, mkxp will make use of any other style it can find for the respective family. This is not the exact same behavior as VX, but it should cover 95% of use cases. Previously, one could substitute fonts via filenames, ie. to substitute "Arial" with "Open Sans", one would just rename "OpenSans.ttf" to "arial.ttf" and put it in "Fonts/". With the above change, this is no longer possible. As an alternative, one can now explicitly specify font family substitutions via mkxp.conf; eg. for the above case, one would add fontSub=Arial>Open Sans to the configuration file. Multiple such rules can be specified. In the process, I also added the ability to provide 'Font.(default_)name' with an array of font families to search for the first existing one instead of a plain string. This makes the behavior closer to RMXP; however, it doesn't work 100% the same: when a reference to the 'Font.name' array is held and additional strings are added to it without re-assignig the array to 'Font.name', those will be ignored.

/* Concerning Font::name/defaultName :
* In RGSS, this is not actually a string; any type of
* object is accepted, however anything but strings and
* arrays is ignored (and text drawing turns blank).
* Single strings are interpreted as font family names,
* and directly passed to the underlying C++ object;
* arrays however are searched for the first string
* object corresponding to a valid font family name,
* and rendering is done with that. In mkxp, we pass
* this first valid font family as the 'name' attribute
* back to the C++ object on assignment and object
* creation (in case Font.default_name is also an array).
* Invalid parameters (things other than strings or
* arrays not containing any valid family name) are
* passed back as "". */
