Updated spyder3 to latest stable version.
Changes
- Fix several incompatibilities with PyQt5 5.12.
- Increase minimal required version of spyder-kernels to 0.4.2 to get important fixes about saving/loading the current namespace and skipping installed modules from our User Module Reloader (UMR).
- Avoid the UMR to reload modules installed in the user site-packages directory.
- Fix an incompatibility with Numpy 1.16 that generated an error when trying to open an array in the Variable Explorer.
- Increase maximum PyQt5 supported version to 5.12
