Set the min-width of window to 600px so that all select list
boxes remain in main toolbar, and not go in toolbar-more.
While resizing the toolbar, if the user tries to reduce the
window width past the min-width set, we would run into an
infinite loop causing spike in browser CPU usage and eventually
crash. This used to happen earlier also before setting this
min-width with very small browser window size.
Also simplify the toolbar resize algorithm. Rather than using raw
jquery methods to move items from one toolbar to another, use
library's (w2ui) methods to add/remove items from toolbar. This
also requires the need of proper initialization of few buttons
such as color picker, table picker because moving item from one
toolbar to another strips off the initialization corresponding to
these toolbar buttons and these need to be reinitialized. Moving
such initialization to onRefresh, hence, would keep them
initialized whenever toolbar is resized.
This also solves one major problem with enabled/disabled state of
toolbar buttons. Since, now, we are actually moving the items
from one toolbar to another, we can enable/disable them using
toolbar's methods ie. enable(), disable().
