Log Message:
Update to 10.4.4

Changelog:
10.4.1 Development release April 3rd, 2012
     The day-of-year value in 'date-list' now also starts with 1, like in 'now'.

     Added CELL_IMPORT_FFI to various output functions (source, save etc.).

     Added UTF-8 meta tag to newlispdoc HTML output.

     Protect internally variable $x used in 'curry' and predefined 'module'.

     When extended 'import' FFI is compiled, show 'libffi' in banner.

     Added new function 'union' (composed of (unique (append ...))).

     New functions 'odd?' and 'even?'

     Fixed unix.lsp for new overwrite protection of imported symbols in ffilib \ 
version

     An additional 'true' flag in (char str idx true) returns the byte value instead
     of the UTF-8 character value at index idx in the string.

     Handle probablilities less 0.5 in crit-z.

     New 'prob-t', 'crit-t', 'prob-f', 'crit-f' for Student's t and F statistic.
     'crit-chi2' redone for extreme values. All report small, significant
     one-tailed probabilities for higher values of t, or F.

     Adjustments in 'normal' for better fit.

     Optional 'true' flag in 'file?' lets it return filename string.

     Windows version should cut off trailing CR-LFs in string passed to \ 
'command-event'.

10.4.2 stable  maintenance release May 2nd, 2012
     In extended ffi "char*" will now only accept strings not integer \ 
addresses to
     string buffers. For passing integer addresses use "void*" - \ 
internally libffi
     treats them as the same, but the new approach gives automatic type-checking
     at the newLISP level without causing a segfault. Already for return values
     "char*" always returns a newLISP string and "void*" an \ 
integer address.

     A fix for 'pack' when packing structures made with 'struct' in 64-bit newLISP.

     In 'import' for OSX/Linux/Unix allow libraries to be opened without importing
     functions. This is necessary if an imported library refers to another one, e.g.:
        (import "libgslcblas.dylib")

     New module gsl.lsp with SVD, QR and Cholesky decompositions.

     Added  'corr', 't-test' and 'stats' statistical functions.

     New standard module gsl.lsp for SDV, QR and Cholesky decomp. and solver \ 
routines.

     Updated plot.lsp with line and XY plot now a standard module.

10.4.3 stable maintenance release May 7th, 2012
     (seek <file-handle>) after (read-line <file-handle>) was broken \ 
in 10.4.0 when
     introducing faster file stream reading on 'read-line' and file closing could
     leak memory.

10.4.4
     Eliminated getFloatFromCell() and replaced by getDirectFloat() in nl-math.c

     Fixed error message for missing [/text] -tag when loading source from file.

     read-file, write-file, append-file, delete-file when used with http:// URLs will
     now return nil under error conditions instead of throwing an error. This is
     consistent with error behavior on local files.  When nil is returned, net-error
     gives more error information. For remote server-side errors on URLs the server
     HTTP error page is returned.

     Check for UTF8 string validity in functions which are UTF8 sensitive.
     An error message "invalid UTF8 string" is issued for invalid UTF8 \ 
strings.

     Several - and continuing - manual updates, most of them also going into current
     online version of manual.

     guiserver.jar 1.47 fixes getting text from an empty gs:text-field.

     Binary number format can be used with either 0b or 0B as prefix to up to 64
     1's and 0's, e.g. 0b101010 for the  number 42.

     A 'true' flag as optional parameter in base64-enc will force the empty string
     to be translated as "" instead of "====". Both cases \ 
translate correctly to
     the empty string when fed into base64-dec.

     Fixed a result stack overflow problem on callback's.

     On OSX Mountain Lion 10.8.0 compiles also using clang instead of gcc.
