i got rid of slot support-text in message-window, so that class does
not maintain a state.
- changed behaivour of split-line
(split-line (format nil "~2%")) ; => ("" "")
That is an emtpy line is returned as empty string and not skipped
Thanks to people from IRC and cl-ppcre maintainer for help!
- [breaking changes] changed 'hooks:*before-prepare-for-rendering-message*
with 'hooks:*before-rendering-message-text*.
- there was a lot of problems related to type of an element of
'rows', they must be always a complex string
- moreover there was an incorrect positioning of the matching string
when character with column width >1 was present before the
string compatible with the regex.
- prevented an info or error message on the command line to overlap
with prompt when asking for user input and, in particular, when
asking for message attachment.
- prevented crash when trying to expand a null string;
- clear send-message-window before deleteing an attach from the list;
- added an info when a status is ready to be sent;
- using a stack to sort drawing order of windows.
