Title: Add element_text with ability to add theme to axis.title.x

First pass at issue Label rotation #93. All keywords except lineheight seem to be working.

ggplot(df, aes('factor(approved_type_of_work)')) +\
geom_bar() +\
theme(axis_title_x=element_text(angle=45,
hjust=1,
family="serif",
face="bold.italic",
color="green",
size=20,
vjust=1,
lineheight=1.2))
