Updated "STORY_SIZE" replacement to include quotes.
* Fixed import error message to complain about the correct type of import.
* Fixed line-termination snafu (likely only an issue on Windows).
* Fixed broken HTML imports (regexp hadn't been updated to account for data-size, also changed to require matching quotes).
Fixed build issue (improper parameters were passed to wx.FileDialog).
Merge pull request #144 from tmedwards/master

Fixed build dialog, line-termination, and import snafus.
