Framsticks

Implemented missing ffs(int) for Windows compilers

Added a helper function; cosmetic changes in names and descriptions

Fixed a bug in ParamObject?: not initializing a field in paramtab, previously unused, recently used as "long name" for more elaborate error messages

Renamed variables that caused problems with g++ 7.3.0 - C99, 7.1.3 ("Reserved Identifiers"): All identifiers that begin with an underscore and either an uppercase letter or another underscore are always reserved for any use.

Updates for compilation+linking of new similarity measures

SimilMeasure? -> SimilMeasureBase?; introduced a new class (SimilMeasure?) that allows scripts to access all similarity measures; a number of minor fixes and improvements

Removed no longer used sources

Fixed a declaration of a static array with a non-constant size in C++

Part of GeometryTestUtils? functions moved to GeometryUtils?.

Similarity measures code refactored. Distribution-based similarity measure added.

Fixed the quotation character

updated for Framsticks version 5.0rc15 most important changes:

• added new hinge joint types and properties (Joint.h*)
• NeuroClass? can now declare the supported model shape_types and joint_shapes
• removed visual thickness (Part.vs)

Use qsort_r() substitute when not available (Android)

Follow-up to r897: A workaround for Android bug in vsnprintf() and vsprintf() in SString, ​https://github.com/android-ndk/ndk/issues/879

Removed Part's "visual thickness" property

Ensure that when stdin/stdout/stderr are not supported (e.g., Android apps), the source does not use them (conflicts with MFILE...)

One less compiler warning about assignment/comparison

Fixed comparison for compilers with default char = signed

Added a demo program to scale a Model and a simple test

test results updated
