================================================================================

Enhance DRC dialog box to:

1) retain lines of error text, so as user re-enters dialog, the previously found errors persist.

2) support double or single clicking a text line, and have the pcbnew cursor go to the offending marker.

3) use color in the text line display.

4) use tooltip on a per line basis, which would show a generic, but error type specific

message about the error for that line.

5) Use sizers properly so that as the dialog box is resized, the text area gets 

all the additional space, both horizontally and vertically.

6) The initial size of the dialog needs to be big enough to show the text lines

 in a clear way.

7) Add a delete button so user can remove a single line of text after he fixes that track.  The delete button

should also delete that single marker.

Implementation Ideas:  retain all drc wxStrings in a vector<wxString> so they

can be re-displayed again on another popup of the dialog.  Switch from wxTextControl 

to wxHtmlListBox for the errors.  Add parsing and formatting functions to allow

grabbing of the coordinate of the marker out of text, and to parse a generic

error message such that it can be embellished into html for use in the html 

line, such that we can get color.  There may be a requirement to rework the

generation of the drc error strings to facillitate easy parsing.  Although

maybe we use structures instead of strings for error reporting so the parsing

does not need to happen.
