directory re-organization (keeps the old build system)

there is no internal modification of any file in this commit

files are moved into directories according to established standards in
sourcecode distribution; these directories contain:

 src - Files that are used in constructing the executable binaries,
       but are not installed.

 doc - Files in HTML and text format that document usage, quirks of
       the implementation, and contributor checklists.

 locale - Files that contain human language translation of strings
          used in the program

 contrib - Files contributed from distributions or other third party
 	   implementing scripts and auxiliary programs

+Please be consistent with the existing coding style.

+

+Block style:

+

+bool Function(char* psz, int n)

+{

+    // Comment summarising what this section of code does

+    for (int i = 0; i < n; i++)

+    {

+        // When something fails, return early

+        if (!Something())

+            return false;

+        ...

+    }

+

+    // Success return is usually at the end

+    return true;

+}

+

+- ANSI/Allman block style

+- 4 space indenting, no tabs

+- No extra spaces inside parenthesis; please don't do ( this )

+- No space after function names, one space after if, for and while

+

+Variable names begin with the type in lowercase, like nSomeVariable.

+Please don't put the first word of the variable name in lowercase like

+someVariable.

+

+Common types:

+n       integer number: short, unsigned short, int, unsigned int,

+            int64, uint64, sometimes char if used as a number

+d       double, float

+f       flag

+hash    uint256

+p       pointer or array, one p for each level of indirection

+psz     pointer to null terminated string

+str     string object

+v       vector or similar list objects

+map     map or multimap
