Summaries truncated indicator (dots) seems not work well with `<!--more-->`.

[razonyang]

i.e.

This module ships with an universal pagination template, which allows configuring by parameters, such as alignment, size and the number of siblings.

<!--more-->

I'd like to revert the #374 change, @TetraTheta what do you think?

[TetraTheta]

If that hurts <!--more--> syntax, it should be reverted. So, yeah, it is OK to revert it.

I didn't tested my PR with <!--more--> so that would be my fault.

[razonyang]

I replaced it with a read more button, it should be better for clients to continue reading and get better experience (no need to scroll up to find and click the title).

Could you do me a favor for translating the item read_more in Korean?
