Various changes (see description)

* Expanded functionality of `sort`

* Added predefined literals

* Expanded funcionality of `)` `Y)` `Z)` to split arrays

* Corrected run-length encoding with cell arrays and with empty input

* The default number of outputs in `ndgrid` is now the number of inputs

* The input to `str2num` is automatically converted to char if it's not
char

* New `Xv` function to remove blanks

* `YG` has been extended with `imshow` and `imwrite` functionality
