Added vcl/settings.hxx to all cxx files which require it.
This helps to speed up compilation after changes to the settings.

In case of forced intercept, R^2 must be calculated in a different way.
This patch calculates R^2 of trend line in the same way as LINEST
function.

...where ThreeDLookScheme_Simple == 0, so actually passing bSimple = false, but
ultimately this argument gets ignored anyway in the implementations of those two
getDefault*LightColor calls that each pass in a null xChartType.

arrays of such need to be initialized dynamically anyway, also change their name
members to proper OUStrings while at it. Plus some const clean-up.

This reverts commit 90f91088d238469b4a2262c91de3117ba40f5bde for now:
Ach, old GCC doesn't like plain string literals to initialize members
of OUString type...

When there were multiple trendlines for one data series and one
was selected, always the equation and R^2 of the first trendline
was displayed in status bar.

Previously, a trendline name was fixed to a combination of the
trendline type and the name of the series. With this it is possible
to add a custom name for the trendline, which is shown in the
legend.

Convert code like:
aStrBuf.appendAscii( RTL_CONSTASCII_STRINGPARAM( "ln(x)" ));
to:
aStrBuf.append( "ln(x)" );
which compiles down to the same code.

Gauss elimination is not a stable algorithm so use QR decomposition
(with other methods). Also use horner's method to evaluate a polynomial
which is the prefered and more stable method of polynomial evaluation.
Still this is not quite enough as you still have to multiply very large
number with very small and you lose percision on high-degree polynomials
or big X values. Some methods evaluate the polynomial in barycentric form
but how to get the polynomial into the barycentric form is now the
question.
