With appropriate codepoint (fix ryanoasis#365)

[why]
We want to differentiate between the old, problematic Material Design
Icons (problematic because we map them to unicode blocks that we should
not), and a future new and updated set of Material Design Icons.

[why]
Material Design Icons has grown quite a bit.

[how]
Add the icons at their original position which is in PUA1.
Use the desktop font instead of the webfont.
Add cheat cheat file.

[why]
The files sizes of otf files are (especially with the addition of the
current Material Design Icons) big enough already. The autohints are not
really useful for symbols, so we can drop them and save some space.

[why]
ScaleGlyph always did scaling only (no translation) based on one
reference glyph.

ScaleGroups does scaling and translation but can not work with one
reference glyph but constructs always a combined bounding box.

Missing is a way to scale AND translate, but with only one reference
glyph.

[how]
Invent GlyphsToScale+ keyword, that supports just that.

[why]
Scaling the glyphs individually breaks a lot of glyph pairs or groups,
for example F0718-F071E.

[how]
Use one ScaleGlyph for the complete set. The set itself is already very
well scaled, i.e. all glyphs are maximized in a given design space and
that they look good next to pairing glyphs.
There is no need to use ScaleRules which is quite costly for such a big
range of glyphs (they all are copied twice in the process).

[why]
The glyph 0xF1522 is broken.

Templarian/MaterialDesign-Font#9

[how]
Manually edit in fontforge and remove line. Export as simple ttf.
