Show '…' after summary when it is truncated

[TetraTheta]

This will show … after summary text if it is truncated.

I think I should provide option for site owner what character to display instead of …, but I can't decide what config name it should have. I don't know if I can use Hugo's variable/param in SCSS style neither.

If we can use Hugo variable in SCSS, the config would be put under params.hb.blog., but summary-truncation-indicator doesn't seem to be nice or intuitive word for describing this.

Currently, it should be overridden by custom style in index.scss like this:

.summary-truncated::after { content: "$"; } /* $ is random character */

If we can't use Hugo's param, telling people about modifying index.scss like that would be required.

Not that related to this PR, but hasCJKLanguage is broken in Hugo.

I think we should suggest people not to set hasCJKLanguage to true even though their site is written with CJK language.
I found this problem while making my customization (and PR).

They claim hasCJKLanguage as

This will make .Summary and .WordCount behave correctly for CJK languages.

but it doesn't.

.Summary returned less words than 70 words/characters which is default value of summaryLength.
Turning it off returned much longer, consist length of summary text.

It also didn't processed some characters.
I found that there is weird & character at the end of summary text. According to content of that post, it should be " instead. I think " was initially ", but was truncated, only lefting &.

This is bug of Hugo, not HB Framework. But I think it would be worthy to tell people using HB Framework that hasCJKLanguage will cause unexpected behavior, contrary to what Hugo Official Documentation says.

At least, with that suggestion, they won't experience same problem that I had.

I didn't see other chars used for this purpose, let others open a feature request if they really need to tweak it via configuration.

Thanks, it may not very useful, since the summaries is up to 3 rows, otherwise hidden and place the ellipsis at the end, beside it will show 4-5 dots at the end in some cases.
