This fixes a problem where comments at the end of a line could be
contained in the highlighting of the prefix. Now matches end 1 character
before their "actual" end
This adds the availability arguments described in the "Attributes"
chapter of the "The Swift Programming Language" book. Also expand the
list of platform names based on the Swift book.

Conforming to Xcode, the syntax file now highlights platforms contained
within the `#available` condition.
It also now removes highlighting numbers and the "*" (i.e, symbol for
future platforms) that are contained within the `#available` condition
since they are not literal numbers or operator (thanks to @acclissold
for the idea)
Additionally, add tests to example.swift to demonstrate highlighting of
them.

Swift compiler currently allows multiple underscore in an underscore
padded number. For instance, 1___00 is a valid way to write 100 in
Swift.
Also add more underscore padded numbers in example.swift file for
testing purposes. Thanks to @aclissold for these.
References #55
"The Basics" chapter of the official "The Swift Programming Language"
book states that you can pad numbers with underscores to help
readability.
This commit also handles the case where underscore padded numbers can
also contain a period (i.e., underscore padded float/double)
Additionally, added some underscore padded numbers in example/swift.vim
for testing purposes.
Fixes#51
