Release 1.14.0 - Embedding version info

Displays version metadata for embeddings & allows filtering for it by prefixing the search with v1 / v2.
This makes it easy to find matching embeddings for sd-v1.x or 2.x models respectively. Implements #97.

Note:

I wait for the webui to load the embeddings to then get their version info, but if the model doesn't load any (e.g. a v2 model, but the user has no v2 embeddings, or the same with v1), I can't test what version they are and default to v1 since it's more common.
I could theoretically check them manually, but that would mean embeddings being loaded twice which would increase startup time, so I compromised here.
