Update nxtvepg to 2.7.4

Changes:

rom 2.7.3 to 2.7.4 (2004-Dec-27)

- bugfix EPG teletext number update in database: after external channel
  changes from one provider directly onto another there was a possibility
  that a wrong teletext number was stored for the first provider,
  subsequently causing acquisition to fail; also changed the EPG scan to
  update the teletext numbers stored in the databases
- added output of current EPG page number to "acquisition statistics"
  in control menu
- added possibility to store "expire time" filter in shortcuts
- fixed timezone calculation for provider "VT4"
- Windows: updated DScaler TV card support; Note a new version of the
  dsdrv4 driver will be installed the first time you start nxtvepg
  (unless version 4.03 was already installed by another application)
- fixes in the way provider and network names were passed to Tcl/Tk
  for display in main window status bar and various dialogs (only
  relevant for names corrupted by transmission errors, but did cause
  sporadic failure)
- fixed default setting for context menu: was empty since 2.7.1;
  Windows only: also fixed !wintv! keyword handling in scripts bound
  to reminder events
- fixed bug in text search filter for merged databases: sub-string
  search ended after 258 characters
- added possibility to configure text foreground colors (at least for
  programme list) to support an inverted color scheme
- added new display format option for composite attributes (i.e.
  user-defined columns): set foreground color for entire column
- UNIX: added "XdTV" (former xawdecode) to internal list of TV apps
  with which nxtvepg can exchange EPG info
- XML export: omit newline (i.e. line break) at start and end of
  description text (on user request esp. for DTD version 5); also
  in DTD version 6 descriptions merged from multiple providers are now
  exported in separate description attributes instead of concatenating
  the text into one with newlines inbetween.
- fixed bug in handling external video input source during EPG scan
  which caused misleading help messages
- added work-around to catch "panic" (i.e. internal errors) in Tcl/Tk
  library, esp. to cleanly shut down acquisition.
  On Windows this fixes annoying popup messages when switching desktop
  display to full-screen (e.g. upon start of some game).
- TV app. interaction developent tool vbirec: added possibility to send
  commands and EPG OSD infos to a connected TV app (to allow testing
  this feature without nxtvepg)

from 2.7.2 to 2.7.3 (2004-Sep-05)

- Fixed backwards compatibility with K!TV (since 2.7.2 there was an error
  message "incompatible shared memory size")
- Fixed description of -clock option in output of -help
