Minor Fixes

Some stuff has been fixed and tweaked to operate more smoothly.
Fixed last-focus to update as other windows are selected and minimize on clicking the selected window. Increased the clock speed so that there is less noticeable delay in showing open windows or selection changes.

0.3.5 Beta

Improved events and window responsiveness. Utilized DataGridView instead of ListView. Added calendar to clock. Flashing is supposed to trigger when there is a window alert (unstable)
