This adds the libqb_http API, which is designed to support HTTP and
HTTPS usage from QB64-PE source.
The design consists of a single thread which services all the HTTP(s)
connections. There are then various libqb_http APIs exposed that allow
interacting with this thread to create a new connection, query
connection status, read data, or close the connection.
Internally the thread makes use of the curl_multi interface to allow a
single thread to service multiple HTTP(s) connections in parallel. This
means you can _OPENCLIENT() multiple HTTP connection in a row and all of
them will be serviced at the same time in whatever order data is
available.
HTTP is optional and selected via a Makefile setting. A stub is swapped
in if HTTP support is not used, which avoids need to add another build
flag to libqb.cpp.
This gives QB64-PE the ability to automatically generate a text file
comprising all of the licenses that apply to your QB64 program. This
file can then be distributed with your program to meet the requirements
of those licenses, and also examined to understand what licenses apply
to your program.
The generation is controlled via a configuration flag, settable either
via the `Run` dialog, or via a new `-f` setting on the comamnd line.
Fixes: #145
- checks all remaining occurrences of the term 'qb64', some remain untouched, some are renamed according to context
- also added new logo for README.md
- this step does finalize the 'Phoenix Edition' re-branding
- rename build artifact names and distribution archive names
- this step completes file name related changes (based on extension, more may come based on "qb64" string)
