Applied Dan Miller's fix to use new Robtex API (http://seclists.org/nmap-dev/2013/q2/1).  I had to modify it slightly to allow [a-z]+.robtex.com in the pattern rather than just dns.robtex.com because many entries used host.robtex.com, top.robtex.com, etc.  More improvements to follow.

Remove http-robtex-reverse-ip script because it pretty much does the same thing as our newer hostmap-robtex

Initial version with a _very_ raw support for HTTP proxy chains (using the
CONNECT method). This is mostly intended to validate the concepts, data models
and programming approach.
Added a --proxies <chain> option to nmap to let users specify proxies to use
from command line.

<chain> is expected (by nsock) to be a comma-separated list of proxies.
e.g.:
  http://relay1.local:8080,http://relay2.local:3128

This option has currently no effect.
Added proxy support to service_scan.
Design improvements.

Externally:
  The calling application can build a proxychain object and assign it to one (or
  more) NSP. Once a NSP get assigned a proxychain it's not possible to remove
  it so that consistency is (should be...) ensured.

Internally:
  An IOD comes with a proxychain context structure storing the whole tunnel
  state. Also each proxy type now has a table of associated functions to use
  as hooks for TCP connects(), read() and write() requests. As a result, adding
  support of new proxy type should be easier. Code also gains readability in
  comparison to large switch/cases that redirect the execution flow according to
  the given proxy type.
Added destructor for proxy_chain_context.
