Release 1.17.0 - Support for new hypernetwork & Lora notation

This release adds support for the new in-prompt hypernetwork and Lora notation used in the current webui version.

The old method of < will show Embeddings, Hypernetworks and Loras mixed together for convenience.
You can use <e:, <h: and <l: respectively as a prefix to limit completion to that type.
Filtering embeddings by version using v1/v2 as a prefix still works for both types, so <v1 or <e:v1.

Thanks to @Mulet-J for his first draft of the feature in #115!
