fix account indexes, add base path in settings

+Copay accepts three base derivation paths:
+
+  * m/44' 
+  * m/48' (only used for MULTISIGNATURE, HARDWARE Wallets)
+  * m/45' (deprecated and it is only supported for old wallets)
+
+Both m/44 and m/48 follow the BIP44 standard:
+
+m/XX'/<coin_type>'/<account'>
+
+Supported cointypes are: 0: Livenet, and 1: Testnet
+
+If you need to import a wallet from a mnemonic using an account different
+from the default (0), use, for example:
+
+  m/44'/0'/11'
+
+to import account 11.
+
+In case you have a multisignature wallet originally created from a hardware device, and you had loose access to the device, you will need to enter the 24 mnemonic backup (from the device) and a path like:
+
+
+  m/48'/0'/8'
+
+for a multisignature wallet, account 8.
