Fix Settings panel crash in Mono - Issue #1587.
Adjust Settings window placement of flowLayoutPanel4.

flowLayoutPanel4 was placed at location 2,2 in tableLayoutPanel3 which places it beyond the last column of tableLayoutPanel3 (2 columns).  Under Mono, this added a new column which made the Settings window look very bad.
