Update: Smoke & Spectre! (Patreon)

A feature request came in and .. figured it was probably time for a little house-keeping to break up the monotony of other work I'm doing. The main additions here are the 'Presets' tab, and the inclusion of a new setting to let you change the default limit for Persistent Lights.- Fixed several Smoke processor pipeline bugs and added some guards to reduce duplicate processing.

- Improved persistence handling, including reconciliation of stale persistent lights.

- Added a new Setting for controlling the amount of Persistent Lights. Also bumped the default from 50 to 100.

- Reworked trailing fog a litttle to be faster.

- Fixed settings-panel issues around elevation style loading.

- Added Vision Presets as a new tab. (Thanks @kat) To save pre-defined vision settings.

- Added preset name matching when using Enable Vision from the context menu.

- Added preset selection to the unit context popover so presets can be applied to selected tokens.

- Expanded Spectre sync behavior and fixed several Spectre update issues.

- Fixed .. a bunch of Spectre things, trying to make it generally more resilient.
