This should fix the comparisons with $IF and VERSION. A few things of note here, which might affect future version labeling:
This expects to find version numbers which follow our current style -- ##.##.## -- 3 numbers, separated by periods.
Adding in alphabetic characters will basically get ignored, and versions with less than 3 values will generate FALSE results in all comparisons.
Fonts 9, 15, and 17 can *only* be used in SCREEN 0. Attempting to use them in graphic screens results in a seg fault and an instant program crash on Windows. This is definitely the most undesirable of behaviors for a program, and can easily be caught and dealt with just by tossing a simple "Illegal Function Call" error for the issue.
This effectively adds Http support to QB64-PE via adding $Unstable:Http
which will trigger building with DEP_HTTP, which enables Http support in
libqb.
Modifies libqb.cpp to add support for opening HTTP connections via
_OPENCLIENT(). This makes use of the libqb_http API in ./libqb, which is
backed by libcurl.
This also includes a bit of refactoring for some of the code that
required additions. I replaced a few of the integer values with enums,
and added a new entry for Http and then implemented it in all the
necessary locations. In addition to `_OPENCLIENT()`, there is also
support for using HTTP connections with `EOF()`, `LOF()`, `GET #`
(variable and fixed length), and `CLOSE`.
I additionally fixed an issue of parsing the colon parts of the
`_OPENCLIENT()` parameter, where having too many colons would cause the
program to crash. Since we only allow so many parts to begin with it I
simply limited the max number of parts it will split to 10.

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.
The 'New Dialogs' menu option was renamed to 'GUI Dialogs' to better
explain what it does. Additionally the setting of which dialogs to use
is saved to the config.ini file so that it presists across multiple runs
of QB64-PE.
We were incorrectly treating the empty string and NULL the same and
using a password dialog for both. It now has the correct behavior of
displaying the password when provided the empty string, but just
displaying a blank input box when provided NULL.
