mw4print: MySQL export, configurable banner text

MySQL database export (dbexport.h / dbexport.cpp):
- New files dbexport.h / dbexport.cpp implement late-bound MySQL export.
  libmysql.dll is loaded at runtime via LoadLibrary/GetProcAddress so no
  MySQL SDK is required at compile time; the app runs normally if the DLL
  is absent.
- After each print job, match data is exported to a MySQL server before
  PrintDlg() is called: one row in 'match', one row per player in
  'player_result', one row per attacker/victim pair in 'pvp'.  An optional
  'event' table records every individual SRecScore entry (off by default).
  Tables are created automatically (CREATE TABLE IF NOT EXISTS) on first
  connect.
- Config stored in mw4print.ini (app directory), section [MySQLExport]:
  Enabled, Host, Port, Database, Username, Password, ExportEvents.
- Config loaded at startup (OnCreate); DB_LoadConfig() / DB_SaveConfig().
- Connection timeout set to 5 seconds so the app does not hang if the
  server is unreachable.
- libmysql.dll (MySQL Connector/C 32-bit) added to Gameleap/mw4/ so the
  deploy script copies it to MW4/ alongside mw4print.exe.

Database Settings dialog (File > Database Settings... / Ctrl+D):
- MFC dialog: enable checkbox, Host/Port/Database/Username/Password fields,
  Export Events checkbox, Test Connection button with live status label,
  OK/Cancel.  OK persists settings to mw4print.ini immediately.

Configurable banner text (File > Banner Setting...):
- The 'WWW.MECHJOCK.COM' URL string printed at the bottom of every score
  sheet is now configurable.  Stored as BannerText= in options.ini under
  [battle tech print] (same section/file as the other print layout params).
  File > Banner Setting... opens a dialog to edit it; OK saves to options.ini
  and takes effect on the next print job with no restart needed.
  Default value is the original MECHJOCK string if the key is absent.
