LRDOCS-437 remove devGuide's preface markdown file
Merge branch 'devGuide-intro' into devGuide-update
Editing for brevity and clarity.  Minor changes made to dev guide intro chapter only.  Paragraph two will be reworked to make more concise.
Changed third second-level heading '##Choosing the right tool for the job' to '##Choosing your development tools'. Attempted to smooth out the two introductory paragraphs, trying to make them more clear and inviting. Tried to make the introduction more accurately reflect what is discussed in the chapter. Removed short descriptions of Portlets and OpenSocial Gadgets since their longer descriptions (third level headings) immediately followed them.  Added any information from the shorter descriptions that was not included in the longer descriptions. Other general edits were made to improve sentence structure and clarity.
Wordsmith dev guide introduction chapter
General editing for clarity and conciseness.  Removed the note that we already introduced the presence of a portlets folder since I did not see it.  Perhaps it was referring to the last chapter which is the Plugins SDK chapter, but I think the chapter should be a self-contained unit.

Continued wordsmithing task, Ch 3.  Had a difficult time ironing out the description of the "support" element under 'A Closer Look at the My Greeting Portlet' (line 277). Stopped around line 500. A Chapter 2 formatting change was also made,for lines 100-101 (from 8-line indent down to 4)
--Chapter 3 completed wordsmithing, but formatting work has not been done.    --Note on 'Understanding the Two Phases of Portlet Execution', beginning at line 471: I found this confusing, because we went into the scenario without saying 'this is what happens if we only allow a single-phased portlet execution'; instead, when I first read it I thought this was how portals did indeed work. But when you get to the end it states that this is not how portals work. I reworked most of it but it should be reviewed for detail accuracy and to ensure the original intent is intact.    --The localization section needs reworking.
LRDOCS340, Chapter 2--Wordsmithing only.  Chapter completed.
LRDOCS 436, formatting--Chapter 3-Portlet Development--> Chapter topics unordered list; space after each paragraph; word counts between figures.  Ended at line 257, "A Closer Look at the My Greeting Portlet".
LRDOCS 436, formatting--Chapter 3-Portlet Development-->Removed figure 3.2, too close to figure 3.3).  Removed figure 3.4 since the directory structure pictured is presented in the text as well (there were 290 words between figures 3.4 and 3.5).  Left figures 3.7 and 3.8 though though 3.8 immediately follows 3.7, because they are very small pictures and shouldn't crowd a page.  Fig. 3/9 and 3.10 are also not large and should not crowd a page despite being just 70 words between them.  Removed tabs from code examples, interpreting each 1 tab as 4 spaces.
LRDOCS340, wordsmithing Chapter 3-->Localization section only.
LRDOCS 436, formatting--Chapter 4-Theme Development-->Task begun, concurrent with wordsmithing.  Unfinished.
LRDOCS340, wordsmithing Chapter 4-->Chapter Completed. Portal Predefined Settings section was confusing, perhaps because of my lack of development background.
LRDOCS 436, formatting--Chapter 4-Theme Development-->Added topics list to introduction.  Used the sections beginning with ## to populate topic list. Removed Figure 4.3 (picture of theme directory structure, which we'd just listed in detail), since it was too close to Figure 4.4.  Left figure 4.6 and 4.7 since 4.7 is very small.
LRDOCS340, wordsmithing Chapter 4-->Worked a little more on predefined settings section.
LRDOCS 436, formatting--Chapter 5-Theme Development-->Topics list. Removed figure 5.2, 5.4, 5.5, 5.6, but left 5.7 and 5.8 because both seemed important, though they're too close.  Removed 5.9.  Neither table rendered properly in HTML for me, but right arrows do not either so not sure if it is my machine.  Did not try to format tables.
LRDOCS340, wordsmithing Chapter 5-->Feng Shui was mentioned in the beginning and end of this chapter, so I sprinkled some mention of it in multiple locations in the chapter.
Chapter 2, corrected typo (sett-->set).
Chapter 4, renumbered figures
