Ability to build with custom style about adm-datetimepicker

[MeTe-30]

Hi Sina,
Thanks.
The purpose of pushing ADM-dateTimePicker.scss in repository is to let developers customise their own styles.
You can see these settings at the beginnings of code:

$green: #56c489;
$warmBrown: #e3d6a9;
$brown: #7e4311;
$blue: #378bd3;
$orange: #fc5f2a;
$gray: #797979;
$red: #E64949;

$mainColor: $orange;
$todayColor: $warmBrown;
$dtpContainerWidth: 20em;

$FAfont: Tahoma;
$ENfont: sans-serif;

You only need to install Ruby.
Then install these packages with gem:

• gem install sass
• gem install compass
• gem install ceaser-easing

Then compile the ADM-dateTimePicker.scss file with command compass watch.
Check Compass Documentation for more help.
