for in the PresetCollection: The 1st preset is always the "-- default --"
even if there are some presets starting with an ASCII character lower than '-'.

fixed crashes when loading a config.ini with "compatible_printers"
disabled export of "compatible_printers" into gcode and config.ini
Enabled compatibility of printing multiple objects with support / no support
with a wipe tower.

Improved handling of custom G-code blocks: Slic3r will try to extract
the target extruder and bed temperatures from the custom G-code blocks.
The incompatible presets are hidden in the tabs if show_incompatible_presets
is false. If show_incompatible_presets is true, there is a button to
show / hide the incompatible presets from the tab selector.
Removed Perl Flow::new_from_spacing bindings.
Some Fill C++11 beautification.
Fix of a support_material_1st_layer_flow, brim_flow and skirt_flow logic to use the extrusion_width if both first_layer_extrusion_width and support_material_extrusion_width are undefined.
Documented the extrusion width logic in the config tooltips, including the default values.
The values of StaticPrintConfig derived objects were searched by a name
walking through a huge chained if.
Now they are being mapped with a std::map.
Also initialization of StaticPrintConfig classes from their ConfigOptionDef
defaults is done by maintaining a single global definition of each
StaticPrintConfig derived class, and a new instance is initialized
from this static copy.
Also the ConfigOption instances are casted using static_cast
wherever possible, and their types are verified by a virtual type() method.
This approach avoids insiginificant performance penalty of a dynamic_cast.
Also the compare and clone methods were added to ConfigOption,
and the cloning & compare work on binary values, not by serialization.

Implemented a correct layer height preview for the wipe tower layers,
if the wipe tower layer height is not constant due to the application
of raft.
When extruding supports, the support is interleaved with interface
if possible (when extruded with the same extruder).
Otherwise the base is extruded first.
