theme_title text_align does not work

[claire-roberts]

I'm trying to center align my plot title and it seems that theme_title(text_align='center') does not work.
An example is below

figure(title="Plot") %>%
ly_points(1:10) %>%
theme_plot(background_fill_color = "#E6E6E6",
outline_line_color = "white") %>%
theme_grid(c("x", "y"), grid_line_color = "white",
minor_grid_line_color = "white",
minor_grid_line_alpha = 0.4) %>%
theme_axis(c("x", "y"), axis_line_color = "white",
major_label_text_color = "#7F7F7F",
major_tick_line_color = "#7F7F7F",
minor_tick_line_alpha = 0, num_minor_ticks = 2,
major_label_text_font_style='italic',
major_label_text_font = 'times') %>%
theme_title(text_align='center')

Any help would be appreciated.
Thanks!

Oops - It looks like the align parameter name has been changed in Bokeh to just align instead of test_align. I just fixed this on the master branch. I have some other changes to work in before I put this update on CRAN, but you can install from github for now to get this fix. Thanks.
