Added a method to Zoom to set a range to a specific ratio. This method
is used by InteractiveCurveViewRange::normalize.

The ability to perform a range search without changing the X range was
only there to accomodate the Yauto feature.

The Auto mode for curve ranges must be deactivated when moving the
cursor outside the screen and when activating navigation (formerly
Zoom).

This method of InteractiveCurveViewRangeDelegate was only used to
compute the Y range when Yauto was on.

The graph range used to be reset to default whenever all functions were
modified. As we no longer want to reset the range without the user's
input, we do not need to track whether the functions changed at all.
/!\ As of this commit, there is no longer a way to restore the default
zoom, until a new automatic zoom button is added.

The banner used to display u(n+1)/u(n+2) if the sequences were not
explicit. This was incorrect and fixed

Forced the top cell of the country table to be cropped in the middle,
cutting the text, to avoid the cell looking squashed.

When choosing a language and then pressing back from the country menu to
get back to the language menu, the previously selected language remains
selected.

u(n+2) = u(n+1) + u(n) + u(2)
u(0) = 2
u(1) = 2
Crashed because the global context was not checking if the sequence was
badly referencing itself

Cache did not check that the step was the same before panning, causing
old values to remains cached.
e.g. :
- Type f(x) = x, and plot it.
- Go to Axes, and set Xmax = 0.
- Confirm

Fix a bug preventing the cursor from moving to other curves using UP and
DOWN when the y value was undef.
To reproduce :
- In Graph, define f(x) = 1 and g(x) = ln(x), then draw the curves
- Press DOWN to select g
- Press LEFT until g is not defined anymore
--> Pressing UP or DOWN won't allow you to select f

When selecting a country, the table would be cropped by the text, with
no separator between the white of the cropped cell and the background
color.

The Equal sign now triggers a syntax error in all apps but Solver. This
make its behaviour symmetrical with that of < and >.

The new zoom implemented for ContinuousFunction is now factorized inside
Function to benefit the Sequence class. The same things is done to code
added to Graph::GraphController, which is moved into
FunctionGraphController.
This removes the reimplementation of several methods, most notably
computeYRange, as the implementation for function is general enough to
work on sequences.

The auto zoom did not display the X axis when drawing positive curves
with roots, such as sqrt(x).
