Subject: [PATCH 01/12] Custom toolchange gcode is searched for tool-changing
 command If the custom toolchange gcode switches extruder to the one that is
 expected, PrusaSlicer does not issue its own T command Otherwise, this
 command is inserted just after the custom gcode, even in case it is not empty
 This should prevent issues such as #2884 and #2886 from being reported

Subject: [PATCH 11/12] Fix of "Strange behavior on bridge detection" #1482 The
 very first slicing step needs to be invalidated if support is enabled or
 disabled while the soluble supports are configured, as the bridging is
 disabled for soluble supports, while the bridging is enabled with supports
 disabled.
