Test SQL database runs on all 3 platforms and on centralized exchanges,

closes #317 (#320)

* 1 - allow server command for UI to support compilation for non-native platform (bind file dependent)

astilectron-bundler will not generate bind files for GOARM versions and not adding arm64 because of duplication of server_amd64.go file for now

* 2 - separate bundler.json and bundler_all.json files based on different platforms for local and deploy modes

* 3 - run server command by default when running Kelp root command if UI capabiity is enabled

* 4 - script to autogenerate bundler.json file for native platform and for all platforms for maximum code reuse

* 5 - remove windows.syso file after building UI for windows

* 6 - change ccxt panic to a log line

* 7 - remove windows.syso file for all builds if it exists
