[TASK] settings: Remove the need for some of the browser force reload

Parameters affected:

1. Options.blobvault.
   js/services/oldblob.js
   165:      var url = Options.blobvault;
   180:      var url = Options.blobvault;
   This should fail because any services/*.js are not re-initialized unless we
   do location.reload().
   Fix: keep location.reload() intact for blobvault.

   js/entry/web.js
   243:if (!Options.blobvault) {
   244:  Options.blobvault = Options.BLOBVAULT_SERVER;
   This shouldn't matter because it is independent of the blobvault value.

   js/services/id.js
   278:      if(Options.blobvault) {
   This shouldn't matter because it is independent of the blobvault value.

2. Options.bridge.out.bitcoin
   src/js/tabs/send.js
   147:        if (Options.bridge.out.bitcoin) { // And there is a default bridge
   148:          recipient += '@' + Options.bridge.out.bitcoin;

   Test: Change the value in Advanced, then go to Send.
   Result: This value updates successfully according to new settings.
3. Options.advanced_feature_switch
   js/tabs/trust.js
   30:    $scope.advanced_feature_switch = Options.advanced_feature_switch;
   Test: Change the value in Advanced, then go to Trust.
   Result: This value updates successfully according to new settings.

   js/tabs/history.js
   76:    $scope.advanced_feature_switch = Options.advanced_feature_switch;
   Test: Change the value in Advanced, then go to History.
   Result: This value updates successfully according to new settings.
4. Options.max_tx_network_fee
   src/js/services/network.js
   30:    this.remote.max_fee = Options.max_tx_network_fee || 12;
   Test: Change the value in Advanced, then go to any page.
   Result: Fails. Because max_tx_network_fee is assigned with pass-by-value.
   Fix: Add
      $network.remote.max_fee = $scope.options.max_tx_network_fee;
   in $scope.saveMaxNetworkFee.
5. Options.server
   js/services/network.js
   25:    this.remote = new ripple.Remote(Options.server, true);
   This definitely requires a reload.
