Improve usability of html-reporter

[nonkor]

I use html-report for debugging intensively and it definitely requires some improvements. So, my suggestions:

1. Instead of wrapping API call into plane lines like

---> HTTP POST https://<endpoint>
...
<--- END HTTP (64 body)
---> HTTP GET https://<endpoint>
...
<--- END HTTP (16 body)

which is really hard to parse due to a massive amount of such calls, I'd prefer to see something like:

HTTP POST https://<endpoint> (64 body)
  ...
HTTP GET https://<endpoint> (16 body)
  ...

where "..." is a body of request indented by 2 spaces. HTTP POST could be colored for visibility (e.g. "red").

2. Right now, beforeEach and afterEach hooks are not marked in a report at all. Considering descriptions of their actions are collapsed under the same header, it's hard to understand which calls there were performed before spec, which after. So, I'd prefer to see something like:

beforeEach {
  ...
}
afterEach {
  ...
}

where "..." are descriptions of hook requests indented by 2 spaces. beforeEach {} could be colored for visibility (e.g. "yellow").

So, as a summary, I would welcome:

• Indents for a body of api call instead of plain wrapping.
• Coloring.
• Marking hooks.

Definitely should be done.
I can add that from my side the following syntax enhancements should be done:

• increase the size of the text
• much bigger tabulation
• space between separate requests
