Remove redundant customization and add some of my own instead

This lightens up the default settings considerable. These defaults
are good enough for me now, but might revisit later.

Removed keys (OSX 10.8 defaults in parenthesis):
- RowCount (24)
- ColumnCount (80)
- RunCommandAsShell (YES)
- ShowCommandKeyInTitle (NO)
- ShowDimensionsInTitle (YES)
- ShowShellCommandInTitle (NO)
- TerminalType (xterm-256color)
- BlinkText (YES)
- CommandString (<empty>)
- shellExitAction (2)
- Bring back default font (Menlo, 11)

Customization:
- Enable visual bell instead of audible one
- Enable useOptionAsMeta
- FontHeightSpacing is 1.1
- FontWidthSpacing is 1
No need for FontAntialias and FontWidthSpacing settings.
For Menlo font, they default to true and 1.0 respectively.
