this PR is the first step for new Pad features.
It implements 3 features requested by users:
1. an option to measure the pad length along its direction if there is a custom direction
2. when there are two lengths, the reverse feature should be active
3. the pad dialog shows now always the used pad direction, no matter if it is a custom one or the sketch's normal
- Furthermore there are some code improvements (avoid rounding and blocking signals)
- Also adapt TestPad.py because its test used the case two lengths + reversed but this was not possible before this PR - the reverse option was not take into account for two lengths in FeatureSketchBased.cpp)
Now it is and therefore the test must be updated:
In the test the second sketch has the normal vector 0, -1, 0. As the reverse option is set the pad direction is 0, 1, 0. So in y direction is the length (1mm) and in -y direction is length2 (2mm). This gives together with the other pad of volume 1, a total volume of 4.
- fix UI issue: either reversed or midplane
As noticed by @chennes, when the pad uses symmetric, reversed is not sensible and vice versa.
This commit fixes the missing Gui side for the case midplane is checked and the App side.
- the PR also fix two typos
