bat cache --build: Print syntect error message for themes if any

Browse Source 
This will fix #614 by making it clear what is wrong by showing the
following error message:

    Failed to load one or more themes from
    '/Users/me/.config/bat/themes' (reason: 'Invalid syntax theme
    settings')

We also need to add a check if theme_dir.exists(), otherwise an absent
dir will seem like an error:

    Failed to load one or more themes from
    '/Users/me/.config/bat/themes' (reason: 'IO error for
    operation on /Users/me/.config/bat/themes: No such file or
    directory (os error 2)')

(This is the same check we already have for syntax_dir.)
