[RFC][WebProfilerBundle] Add simple placeholders into search form

[stloyd]

This is an RFC mostly, it's not a real feature, it's more like little helper for the profiler form, I guess that would mostly useful for newcomers, but sometimes even old dogs could find it useful sometimes =)

@stloyd thanks for this pull request. I really like it! The only thing that I'm not sure about is the date placeholders. You propose to use the following:

<input type="text" name="start" id="start" value="{{ start }}"
       placeholder="i.e. {{ '-2days'|date('d.m.Y') }}">

{# ... #}

<input type="text" name="end" id="end" value="{{ end }}"
       placeholder="i.e. {{ 'now'|date('d.m.Y') }}">

In my opinion, using dynamic dates is handy but not always helpful. The problem with dates is that you never know if the first number is the day or the month. Take for example your screenshot: 07.04 is the 7th of April or the 4th of July?

I'm not sure about this but, do you think it could be better to replace the dynamic dates for date format placeholderes such as dd.mm.YYYY?

you mean "e.g." not "i.e."

[stloyd]

@javiereguiluz Really good point, and I must say that I was not sure what to put there, so I choose most common format I know =)

But taking your point I think that this version: 9th April 2014, looks better than dd-mm-YYYY (or dd.mm.YYYY):

A placeholder like 9th April 2014 could make people think they have to type the whole month-names into the field... I like the format placeholder

[romainneutron]

e.g. 9th April 2014 is correct whereas e.g. dd-mm-YYYY is not correct (dd-mm-YYYY is a format, not an example)

As Javier proposed, I'm much more in favor of using dd-mm-yyyy as a placeholder as developers understand it, and they would write a date using the correct format.

[pborreli]

instead of placeholders for date inputs I would use input="date" in order to benefit the features offered by browsers and html5

[yguedidi]

👍 for date input

[fabpot]

Using a date input as suggested by @pborreli makes a lot of sense as all browsers used by developers probably support this anyway.

@stloyd Can you update this PR?

[stloyd]

@fabpot Done, unfortunately we can't use only date type, it's not supported by IE & FF, so I have left those placeholders there with suggestion from @javiereguiluz (dd.mm.YYYY), also added usage of url, as it's support is much wider than that date type.

Thank you @stloyd.
