cptStatusSheet - fix default txtDir on first run

[AronGahagan]

Problem:

1. On first run, txtDir defaults to a directory that does not yet exist ("Status Requests")
2. On first run, chkAppendStatusDate should default to false

Solution:

1. On first run, whether running locallay or on PWA, default to the user's existing Desktop
2. On first run, default chkAppendStatusDate to false
