Better status bar messages with improved DXCC Entity lookup #236

[w7sst]

Updates to ARRL.pas (DXCC list parser)

• do not sort the regular expression list. These are ordered and must be processed in reverse order.
• added code to skip comments
• when extracting the callsign's prefix, do not remove the trailing characters. (This was masking prefixes with a trailing character (e.g. ).
• special case for KG4 (Guantanamo Bay). Turns out many US callsigns have KG4 prefix but are located in US. The convension used by many is to let the 2x1 or 2x3 forms of this prefix to be in US and let any 2x2 calls to be in Guantanamo Bay.
