Updated GUI (#26)

* Added times of last load

* obj files now load with meshio loader

* create_meshio_obj now uses default blender obj importer

* create_meshio_obj now only checks for the ending

* Update (not working atm)

* Current not wokring version (but mzd is now fixed)

* Better (not working) obj loader

* Some debugging lines

* Added functionality to use from_pydata and objloader now works

* Minor updates (with old mesh loading)

* Updated submodule extern/fileseq

* Updated submodule extern/meshio

* Updated submodule extern/python-future

* Updated submodule extern/rich

* Renamed symbol

* Added files of submodules

* A lot of UI changes

* Revert "Revert "A lot of UI changes""

This reverts commit 34d179c.

* Fixed obj. loading duplicate bug

* Purges all old meshes (during .obj sequences)

* Changed class names to fix warnings

* Uncommented seperate obj import

* Uncommented seperate obj import

* Update meshio

* Small fix

* Added compatibility for split vertex normals with objs

* Added obj.py

* Default normals now work with .obj and .vtk

* Added import zip operator

* Import + Delete Zips works now

* Lowered number of shown seqs, because it's not the main function anymore

* Imported extracted zip folders are stored in tmp_zips in a custom location and this whole folder is then deleted

* Made addon ready for release

* Updated submodule extern/fileseq

* Updated submodule extern/meshio

* Updated submodule extern/python-future

* Updated submodule extern/rich

* Minor GUI adjustments
