Title: remove necessary character space before the language parameter

In get_googlemap.R, a extra space (%20) followed some symbols “=” in addition to “language=%20zh-CN” in formatted url.
For some reason, Google Map API is particularly sensitive to the extra space in parameter “language”. So the language parameter dose not work properly in ggmap package.
