Recompiled JS
Fixed issue #168 and updated main Readme.md
Fixed some data bugs including issue #127
Fixed grid demos
Fixed search/sort for the dates

Also fixed issue #119
Refactored code for list.options.url

Effects issue #166
Dropped "do" prefix from all objects

This was confusing because sometime do was used, and sometime it was
not. So, to make it uniform, I have dropped do's completely.
Fixed keyboard navigation for sidebars
Added context menu for sidebars (issue #65)

Sincer there is no documentation see w2sidebar.menu array and
w2sidebar.onMenuClick event. Popup menu uses same function as toolabr.
Also see test/sidebar.html in this commit as an example.
Added scrollIntoView() for w2sidebar
Added $().w2menu, refactored toolbar and sidebar to use it
