i2ptunnel:

ECDSA default for all new server tunnels
ECDSA default for streamr client tunnels
Fix display of server destination on edit page when not running (privkey file path wasn't absolute)
Fix display of persistent client key b32 on edit page when not running
Fix display of server sig type on edit page when we have a privkey file
Add KeysAndCert.getSigType()
