Refactor/rename getSavedNetwork and getSavedNeworks to indicate search

[isuPatches]

Rename:

• getSavedNetwork(regex: String)
• getSavedNetwork(regex: String, callbacks: GetSavedNetworkCallbacks)
• getSavedNetworks(regex: String)
• getSavedNetworks(regex: String, callbacks: GetSavedNetworksCallbacks)

to:

• searchForSavedNetwork(regex: String)
• searchForSavedNetwork(regex: String, callbacks: SearchForSavedNetworkCallbacks)
• searchForSavedNetworks(regex: String)
• searchForSavedNetworks(regex: String, callbacks: SearchForSavedNetworksCallbacks)

This will require breaking up getSavedNetwork and some precheck logic.
