Make headers in help hover look prettier

[ManuelHentschel]

Modifies the header of help hovers to remove the first line.
Information about the package is moved to the first proper header instead.

The title might not look better than before if it is long.

What about using

pattern <- "<table.*?<td>(.*?)\\s+{(.*?)}<\\/td>.*?<\\/table>\\n*"
replacement <- "<b>\\1</b> <i>{\\2}</i><hr/>"

Both topic and package are preserved in the headline of the hover.

replacement <- "<b>\\1</b> <i>{\\2}</i><hr/>"

That looks quite nice as well. What bothers me a bit here (and in the original version) is the vertical space taken up by the large heading plus the line "Encoding {base}", which I tried to reduce by moving the package info into the heading.

What do you think about these?

replacement <- "<b>\\1</b> <i>{\\2}</i><br/>\\3<hr/>"
pattern <- "<table.*?<td>(.*?)\\s*{(.*?)}<\\/td>.*?<\\/table>\\n*<h2>\\s*(.*?)\\s*<\\/h2>"

It looks good! Let's use this one.

Just noticed that pandoc < 2.0 will produce different result with the modified html:

Let me do a quick fix for this.

[renkun-ken]

pandoc >= 2.0

**get** *{base}*  \nReturn the Value of a Named Object\n\n-----\n\n

pandoc < 2.0

**get** *{base}*\nReturn the Value of a Named Object\n\n------------------------------------------------------------------------\n\n

Looks llike <br/> is not translated to <space><space>\n.

Fixed via 62b06e5.

replacement <- "<b>\\1</b> <i>{\\2}</i><p>\\3</p><hr/>"
