add user agent to avoid problems with modsecurity

[jsibley2]

I may be wrong, but it appears that modsecurity is blocking access (rule 990011 in my case) to limesurvey remotecontrol on my survey because the httr call is not providing a user-agent parameter.

Unless there is a reason not to, if my guess is correct, might it be possible to add a user-agent of "httr" to the code that interacts with remotecontrol?

Thanks.
