Mailpile - some formatting/editing

As before, doing formatting/editing, where needed, for the sake of consistency and cleanliness. Some examples:

+Quotes:
-Change quotation marks and apostrophes to typographic form
-Use single quotation marks before double
+Dashes:
-Replace double dashes with em dashes
-When standard single dashes are used for interpolation, replace with em dashes
-Put a space on either side of each em dash
+Make all ellipses spaced
+Break very large paragraphs into two or more
+Remove overused interjections that detract from the written form
+Correct any spelling or capitalization errors for things like project names, tech terms, people names, etc.
+Fix general grammar mistakes
