Changes

GraphPanel widget: added context menu items for supporting log scales on
axes (#1299).
 (commit: 287c32f)

Some minor cleaning up.
 (commit: a92b9cb)

GraphPanel widget: set the linear/log scale as requested (#1299).
Still need to do much work to ensure that the log scales are actually 
sound.
 (commit: 0372bd3)

GraphPanel widget: make sure that a plot gets redrawn when changing
scaling of an axis (#1299).

GraphPanel widget: keep track of the axis range to optimise and make
sure that it gets reoptimised when changing the scaling of an axis
(#1299).

Properly use qFuzzyIsNull() and qFuzzyCompare().
 (commit: 0bae223)

Some minor cleaning up.
 (commit: c70b71a)

Don't rely on qFuzzyIsNull() and qFuzzyCompare() anymore.
Indeed, to use qFuzzyIsNull() (or something equivalent using 
qFuzzyCompare()) in GraphPanelPlotScaleDraw::label() resulted in small 
numbers (e.g. 1e-100) to be considered as zero, which is not what we 
want. Similarly, we simplified our SimulationData::isModified() method.

GraphPanel widget: make sure that axis labels are properly formatted
(#1299).
Indeed, our previous implementation would render 1e-80 as

 (commit: af1da55)

Some minor cleaning up.
 (commit: afa6005)

GraphPanel widget: make sure that axes are updated if necessary.
This actually fixes a small issue when having, for example, two graph 
panels and asking for the Y axis of them to be synchronised. Indeed, the
Y axes didn’t get synchronised until we panned one of the graphs
(for example).
 (commit: 4f357be)

GraphPanel widget: make sure that axes' alignments are kept when adding
a new graph panel.

GraphPanel widget: reset axes when enabling/disabling logarithmic axes
(#1299).

GraphPanel widget: slight improvements to our
GraphPanelPlotWidget::setAxes() method.

GraphPanel widget: reset our axes when enabling/disabling logarithmic
axes (#1299).
 (commit: b93a3ec)

GraphPanel widget: optimise our log axes (#1299).
 (commit: 72e7315)

GraphPanel widget: added a way to set/get the logarithmic state of an
axis (#1299).
 (commit: 0ec01ca)

GraphPanel widget: export to SED-ML whether a graph panel should have
logarithmic axes (#1299).
 (commit: 40ac49a)

GraphPanel widget: support SED-ML files with curves that have a log
scale (#1299).

GraphPanel widget: make use of the log scale information found in a
SED-ML file (#1299).
