Add human modifier for date and time fields

[omarkasem]

• FIxes Add support for :human merge tag modifiers on all Date fields #1990
• I had to edit the GravityView_Field_Date class because it was overriding the human modifier by running the function again without the new arguments and i couldn't remove the filter gravityview/merge_tags/modifiers/value as it was happening after the human modifier function.

💾 Build file (51757fc).

@omarkasem, code looks good, thanks. Could you please add a unit test for this?

@Mwalek, please test.

@omarkasem I think there is a problem with the handling of future dates (see image).

@Mwalek Thanks for noticing, It's fixed now.
@mrcasual I also added extra tests for future dates and times.

@Mwalek, please retest and also try with different timezones.

@omarkasem @mrcasual future dates are now displayed correctly.

As for the timezone, it doesn't matter what is set in WordPress (settings > general), it looks like the server timezone (UTC) is employed. This applies to both comparisons of past and future dates.

In the image below, I have the WordPress timezone set to UTC+2, my timezone, so if the human time difference were applying this setting, I would expect to see the next day starting in 2 hours instead of 4 (see image).

• Future dates are displaying “{time} ago” instead of “from now”
• Timezone offsets are not handled properly
