GUICtrlSetData: Edit: default: Improved documentation

[c.haslam]

I find the current documentation for the default parameter unclear. I suggest the following:

In the "Parameters" section, row 3 column 2, replace Edit, Input words with:

any value (except ""): inserts value of data parameter at insertion point

In the "Remarks" section, add:

for Edit and Input controls:
When the default parameter is omitted, this function replaces the current contents of the control.
