Alpha v0.18.2

NOTE: This is another reminder that the installer still has an issue that makes chaiNNer not open automatically after install. It does still install, so just open it manually after.

This update addresses a few bugs, but mostly adds a few cool nodes.

Minor Changes

• Consistent UI font between platforms + switch to using Open Sans (#1610, #1614)
• Seeds are now their own datatype rather than numbers (#1611)

New Nodes

• Text Slice (#1580)
  • A node for getting a substring of text
• Text Length (#1580)
  • A node for getting the length of text
• Round (#1603, thanks @adodge)
  • A math node for performing rounding operations
• Derive Seed (#1611)
  • Use various sources to derive a seed for use with nodes that deal with randomness
• (PyTorch) Guided Upscale (#1506, #1616)
  • Based on PixTransform, guided upscaling upscales an image based on another
  • For example, you can use a high quality diffuse texture to upscale a lower quality normal map of that texture

Bug Fixes

• Fixed running MAT on GPU (#1599)
• Fixed loading SRGB DDS (#1606)
• Fixed being able to drag on the + button on some nodes (#1607)
