This adds unit tooltips to the const menu which appear when hovering over
a specific constant with the mouse.
Changes to be committed:
modified: math-buttons.c

This adds some fundamental physical constants:
- Velocity of Light "c₀", 299,792,458 m/s
- Magnetic constant, "μ₀", 1.2566370614×10⁻ N/A²
- Electric constant, "ε₀", 8.85418782×10⁻¹² s⁴A²/m³kg
- Newtonian constant of gravitation, "G", 6.67408×10⁻¹¹ m³/(s²kg)
- Planck constant, "h", 6.62607004×10⁻³⁴ m²kg/s
- Elementary charge, "ｅ", 1.6021766208(98)×10⁻¹⁹ C
- Electron mass, "mₑ", 9.10938356×10⁻³¹ kg
- Proton mass, "mₚ", 1.672621898(21)×10⁻²⁷ kg
- Avogrado constant, "Nₐ", 6.02214086×10²³ mol⁻¹
They are taken from https://en.wikipedia.org/wiki/Physical_constant#Universal_constants
To insert them one would enter the corresponding symbol or use the gui.
They are set to a MPNumber from string.

.ui files are combined into a binary resource bundle, and
they are marked as compressed, so they will be automatically
uncompressed when the resource is used.

Also, change them in all translations with the help of find and sed.
I am not entirely sure if this is correct for RTL languages like arabic,
but it does look similar to the other tooltips :)
Commands used:
find . -name "*.po" -print | xargs sed -i '{N
s/msgid "Shift Left"\n\(.*\)"/msgid "Shift Left [<<]"\n\1 [<<]"/g}'
find . -name "*.po" -print | xargs sed -i '{N
s/msgid "Shift Right"\n\(.*\)"/msgid "Shift Right [>>]"\n\1 [>>]"/g}'

This patch also changes the shift operation itself to use MPNumber for the
multiplier too. Previously a signed int was used, which led to "interesting" results
for bigger numbers. This was hidden because the GUI did not allow shifts with
more than 15 places.
