Fixed a few spelling errors and made a few "stylistics" changes

in an attempt to improve the "flow" for native English speakers.

-I've been doing a lot of work in the Nginx world over the last few years
-and I've also been thinking about writing series of tutorial-like articles
-to
-explain to more people what I've done and what I've learned in
-this area. Now I have finally decided to post serial tutorials to the
-Sina Blog L<http://blog.sina.com.cn/openresty> in Chinese. Every article
-will have one rough topic and will be in a rather casual style. They're
-not parts of a book after all. But I do have plans to re-orginaize these
-stuffs to form a real book.
-
-Now the tutorials being written is devided into "series". For example,
-the first series is "Nginx Variables". Each series can be roughly mapped
-to a chapter in the Nginx book that I may publish in the future (of course,
-I will also reorganize the contents to form "sections"). The tutorials
-are
-intended for Nginx users at various levels, including those Apache and
-Lighttpd
-users who have never used Nginx before.
-
-The samples in my tutorials are at least compatible with Nginx C<0.8.54>;
-do not try the samples with older versions of Nginx. The latest stable
-version as of this writing is C<1.0.10> after all.
-
-All of the Nginx modules mentioned in these tutorials are production-ready.
-I will not even mention those standard Nginx modules that are either experimental
-or buggy.
-
-I'm going to make extensive use of Nginx 3rd-party modules here. If you'
-re too
-lazy to download and install those modules one by one, then you are recommended
-to download and install the C<ngx_openresty> software bundle that is maintained
-by me.

+individual modules one at a time then I highly recommend that you download and

-One principle that I've been trying to follow in these tutorials is to
-use small and concise configure examples to validate the concepts and principles
-that are being explained. I hope this can help the reader to build the
-good habit of not accepting others' viewpoints or statements without testing
-them. This style may have something to do with my QA background. In fact,
-I keep adjusting and correcting my words according to the running results
-of my little samples in the process of writing.
