* not depending on "-dev" packages for the built Debian package
* some refactoring in if-clauses and with "quotes"
* libvterm dependency: if something is missing, made clear what
Some other changes to the CMake-files done as well:
* documentation looks more like Doxygen-style
* prevent mix-up with C++ GSL library ("Guidelines support library" not
"GNU scientific library")
There is no version detection. If there is any vterm library, it is
used. If it is the wrong version, there will be an build error.
`libvterm.so.0.0.2` is preferred, which hopefully is compatible to
revision 740 or Ubuntu `libvterm0` version 0.1.2-2.
If no library is found, the correct one is downloaded and build.
* using `get_wch()` now and mapping most of the function keys documented
in `vterm_keycodes.h` (not num keypad)
* there are still a lot of mappings from ncurses missing (in conjunction
with modifier keys, related issue #11)
* using mutex to make sure writing to terminal client is serialized
* Output strings with unprintable characters either as a table or as
continuing string of characters; the byte value of unprintable
characters (`isprint(<character>, <locale>) == false`) is shown.
* Output readable string of `key` -> `value` pairs with an enumerated
type for the key and union type for the value.
When pressing return in `nano` the terminal received an `<CTRL>+J` instead of
the return key. `<CTRL>+J` justifies the text. But is (confusingly) actually
the key for a line feed as well? Terminal programming is not easy …
* demo app: using `SHELL` environment var or `/bin/bash` as default
* removed some debug messages
* enabled all vterm screen handlers; if not implemented there is a debug
message
* fixed and improved cursor position — was sometimes off; e. g. if
pressing backspace
* stubs for some functions required for implementing #3
