Corrigido erro de não fazer o embed do manifest em dlls compiladas pelo Visual Studio 2008 no caso de a dll fazer parte de um módulo (estar em um subdiretório). O LuaRocks não fazia corretamente o build de módulo que tivessem estrutura de diretório (como luasql.postgres).
Add a configuration option to specify manually installed rocks.

The patch adds a new configuration option - cfg.rocks_provided.
This option contains a list of packages that are either builtin or
manually installed outside of LuaRocks package management system:

    rocks_provided = {
      [module_name] = module_version.."-"..rockspec_version,
      -- ...
    }

These settings are taken into account during dependency resolution
and when search and install commands are used. An attempt to install
a rock from the list causes an error.

LuaRocks automatically adds following modules to the list:

    rocks_provided = {
       lua = lua_version.."-1",

       -- For Lua 5.2 or later:
       bit32 = lua_version.."-1",

       -- For LuaJIT:
       luajit = lj_version.."-1",
       jit = lj_version.."-1",
       ffi = lj_version.."-1",
       bit = lj_version.."-1",
       luabitop = lj_version.."-1"
    }

where lua_version extracted from _VERSION (e.g. 5.2),
      lj_version extracted from jit.version (e.g. 2.0.2).

Built-in values can be overridden by configuration options.

Closes #177.
Fixed the error of not embedding the manifest in DLLs compiled by Visual Studio 2008 in the case where the DLL is part of a module (inside a subdirectory). LusRocks was not correctly building modules with directory structure (like luasql.postgres) when compiling for win32.

Does the windows installation with Windowish defaults
Adds a prompt before installing, and a switch /Q to ignore that
example added to help text to explain a self contained installation
registry information is now loaded without prompts

Add .travis.yml... let's see what happens!
Fixes for Travis-CI
Ah, Ubuntu...
Let's use the unstable LuaSec for now. Pinged Bruno about it.
Drop the X11 dependency
skip this one
I'm still trying, Travis! I'm still trying!
skip rsync stuff
skip more rsync stuff
Just one more...
Going crazy!
stopped copying dll files becasue reason is unknown
added note on %appdata% value
Merge pull request #197 from Tieske/proper_win_defaults

Update Windows installer defaults
Fixed an improper error message

Forgot to check that type=="string" before doing pattern matching on a field content.

Was triggered when version was provided as a string in a luarock.
