New file formats for sending via contact forms

Weblium restricts file formats that can be attached to a message sent via a contact form. For example, to prevent potentially dangerous executable files (.exe) sent to you.

In this update, we have added such file formats as STEP, STP, SLDPRT, STL, DXF, IPT, 3MF, 3DXML, GLB, GlTF, PRT, and SAT to the previously existing standard formats. These types of files are important for those involved in 3D modeling.
