GTK 4.10 port, with bug fixes

[borkra]

This includes following major changes:

• Complete GTK 4.10 port
• Restructuring to move all UI definition out of C code into GTK builder ui files
• Fixed a lot of cut & paste and file transfer issues, with proper queuing large data sets
• UI changes:
  • Added disable shortcuts menu item to disable keyboard shrotcuts, this enables proper operation with curses based applications without gtkterm shortcuts overwriting curses controls.
  • Send file transfer menu into 2: "Send Raw file" and "Execute script", this clarifies the behavior and removes ambiguity.
  • Send raw file just dumps raw data set into the terminal.
  • Execute script, reads file line by line applies auto cr-lf if chosen and does all other things expected from text based execution.

I am using this all day long every day and do not see any more issues for a month or so. So I guess good enough to commit.

#48
#13
#77
