Merge pull request #18 from debanjum/deb/save-models-to-disk-on-first-run

Save Search Models to Disk on First Run

## Why
  - Improve application startup time
  - Startup application and perform semantic search even if user offline
  - Use search model config in YAML file for all search types (asymmetric, symmetric, image)

## Details
  - Load search models from disk when available
  - Use search model config specified in YAML file
  - Add search config for Symmetric Search used by Ledger/Beancount transaction search
