1.41.1-5 : moar seam options

new:

• "nearest" seam option now really emphasise the proximity
• old seam "nearest" moved to "Hidden" (as it prioritize the best position before going to the nearest)
• new option for seam : Travel move reduced. It modified the cost a bit more. Not sure it has a significant effect.
• looping perimeter: now a position option for the position of "loop switch". Nearest can lead to some undesirable effects combined with "nearest seam", the "rear" (highest y) was added.
• Remove small gaps: when unchecked, it lower drastically the checks for small gaps in geometry, see prusa3d/issues/520

other

• changed some default settings (from selected to not selected)
• some text changes.

known issue
