Within code often it is required to temporarly override value of some
object properties. To properly restore old values they must be stored
somewhere and the developer must remember to manualy restore them.
This commit introduces utilities that can be used to make it easier
using RAII idiom to guard the overrides.
For the z88 export the FemMesh must be passed to its Python wrapper which will increase the counter upon construction and decrease it upon destruction. If the counter becomes 0 the FemMesh will be destroyed too which causes a crash.
To fix the crash the counter must be increased and safely decreased after the lifetime of the Python wrapper.

*i1.txt or *o2.txt are not valid suffixes for a file dialog. In the past (until 2018) the suffixes were set to *.txt but this has been changed with 6fe8a881e.
To avoid creating invalid filenames the original suffixes are restored.

* Sketcher: Set total angle to make evaluation choose it when typing in OVP
When typing an angle value (e.g., "315 deg") in the sketcher rotate tool,
the result differed from manually moving the mouse to achieve the same rotation.
The angle would "flip" to equivalent but opposite directions (315 deg became -45 deg)
due to smart angle selection logic choosing the "closer" alternative.
The parameter enforcement system (`doEnforceControlParameters`) calculated cursor
positions for keyboard input but never directly set the `totalAngle` value.
The mouse logic's smart angle selection algorithm then calculated totalAngle
independently, potentially choosing equivalent but opposite angle directions
(e.g., -45 deg instead of +315 deg) based on proximity to the previous angle value.
Solution is to basically predefine `totalAngle` if user has typed it so
this "smart logic" will always choose the `totalAngle` that user typed.
