Proxy setting isn't applied for XeroClient.executeFile

[jinywu]

I put proxy setting in config.json as follows.
"ProxyEnabled": "true",
"ProxyHost": "proxy.xxxx",
"ProxyPort": 8080

it's successful to get invoices and other information, but it failed to download attachements. It seems that proxy setting is not applied for the executeFile funciton.

Hi @jinywu

I've pushed release 2.0.2 with fix for proxy setting.

Thanks for catching this.
