Enhancement request: when line-wrapping, recognize '/' (slash) as a character for word splitting

[kcalcagno]

When the library finds it needs to wrap a line to make it fit in a cell, it first tries to split on words and then, if a particular word still won't fit, it splits the word with a hyphen. PdfUtil.wrapLine splits the line into words with the following regex: (?<=[\\. ,-]). (A zero-width lookbehind for backslash, period, space, comma, or hyphen.)

I recommend that we also add / (forward slash) to that regex. This would help split words that are connected as alternatives (like "either/or") as well as URLs and (Unix-style) file paths whose segments are delimited with /. (Only guessing, but I would imagine backslash is in there for Windows-style paths.)

Happy to submit a PR if you like, though it's a one-character change. (And a new unit test.)
