Theme directory on Windows is ~/AppData/Roaming/RStudio for RStudio >= 1.3

On Windows its ~/AppData/Roaming/RStudio for RStudio >= 1.3 now. Seems like this is final for v1.3.

Soon v1.3 will be the default but maybe @gadenbuie can include a condition anyways? :)

I think there were originally some limitations with how rstudioapi::addTheme() worked that I didn't like, hence the use of {fs} to copy themes.

But the themes directory has changed a few times between RStudio 1.2 and 1.3 and rather than chase these changes I think it's better to use the internal functions of the rstudioapi package. Presumably those functions will know more than I do about where themes and configuration files are located.

And there is always the destdir option in install_rsthemes() that users can fall back on if the rstudioapi::addTheme() function doesn't work as expected.
