.hc_get_fonts doesn't handle fonts names with multiple spaces

[sz-cgt]

Specifying a font like Franklin Gothic Book in a chart causes the chart to not generate.

The issue is in .hc_get_fonts at line 133 of theme.R. Instead of

str_replace("\\s+", "+") %>% 

it should be

str_replace_all("\\s+", "+") %>%

otherwise only the first space in the font name is converted to a +

Thanks so much for found these bugs!
