Idea: Use one-char ellipsis symbol in more places

[dannysepler]

In print_table() and print_html(), when the column width exceeds the max_column_width, the ellipsis symbol factors into that max_column size. The three letters of a normal ellipsis are kinda bulky, especially when we have small max sizes like here: wireservice/csvkit#941

There's a few things we can do!

1. As the author suggests, make the ellipsis char a parameter. Might not be necessary to expose to the user. They'd probably just toggle it off?

2. As the reviewer suggests, make the max_precision customizable. This might not fix the issue, since print_table will still chop off the more precise value to insert the ellipsis characters

3. Give "use_ellipsis", or "truncate_decimals" as a passed-in parameter. When it's false, we don't use the ellipsis in decimals. (I'm guessing non-decimals would need the ellipsis all the time?). This requires a bit more work with decimal parsing, but is totally possible

4. (This diff) Use the one-char ellipsis in print_table and print_html. This is the simplest way to fix the readability in the issue above, so I chose it. It's also already used in "utils" so hooray for consistency?

I would merge this PR if you leave ellipsis_chars as-is (don't rename to ellipsis_char) and just change ... to ….
