Bug: sould not be able to select & drag AM/PM text around the textbox in chrome,

[weedkiller]

The mouse is allowed to drag text around, as a result its submitting malformed test.

• Solution: Disable drag /drop in textbox
• Bootstrap theme-ing support
• hours only format, do not display AM/PM just hours,
• allow configurable default number of hours, on presseing the black default button besides the box. For e.g. let user select default 1 hr! or 8 hrs
