Subject: [Common] JS logs are turned off with debugging flag
X-Git-Tag: submit/tizen_3.0/20170302.070257~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c62b44462e4ab5929b710854776fd4873b209d4f;p=platform%2Fcore%2Fapi%2Fwebapi-plugins.git

[Common] JS logs are turned off with debugging flag

[Feature] console.log is disabled by default but can be easily enable
  with setting a flag to 'true' value.

[Verification] Related TCTs result didn't change.
