ParseInt for validateCode

[evantobin]

Parse validateCode as an integer. We could make the UI take in an integer, but then the user is presented with a number selector which isn't ideal. Easiest to keep it as a string in the UI and just parse it as an int on the backend.

♻️ Current situation

The Homebridge UI puts the verification code in the config as a string which causes an authentication error on august's servers. Changing it to an int works, but then you have to manually update the config.

💡 Proposed solution

Add parseInt before the code is sent to the server. This way both integer and string verification codes will work right with august's servers.

⚙️ Release Notes

Plugin now works correctly with string-based verification code configs.

@evantobin, I have re-based this to the beta-1.0.6 branch. Can you resolve the conflicts? or close this PR and create a new one based on the beta-1.0.6 branch?

[evantobin]

I'll create a new one on the beta branch. Github by default only forked the latest branch.
