Support for extra libraries in APK in Android QT Creator -- Merge request

[Frameworks]

Dear Bogdan,

I just send a merge request for the changes in creator that add support 
for extra libraries in the APK. Here are the details:

Add in support for extra libraries.

This merge request mainly focuses on the modification to Android QT 
Creator to include support for extra deploy libraries in the APK. As 
described in the modified UI, “Extra libraries are other libraries that 
are required by this application but not part of this project.”

The changes in Creator does not automatically affect current Necessitas 
projects. If the user want to include an extra library Creator will ask 
to upgrade it project to support it. The process of upgrading will:

1. Check if its possible. Users will be able to upgrade if their version 
of Android LightHouse supports extra libraries i.e., if the version of 
libs.xml in LightHouse has the array name extra_libs.
2. Upgrade the project's ibs.xml to add the array name extra_libs.
3. Upgrade the projects manifest to include the resource of extra_libs.
4. Copy the class files from LightHouse to the project (Industrius and 
mobile). This because the version in LightHouse has the modifications to 
load the extra libraries. All files are copied to be sure that previous 
class files in the project does not conflict with current class files.
5. Leave a backup of libs.xml, class files and the manifest in the 
project directory. Those files will include “._old” in their extension

This set of changes also fixes two bugs in Creator:

1- Checked bundled libraries get unchecked just before the APK is build. 
(Line 133 in androidpackage creationstep.cpp)
2- Bundled libraries have the format libMyLib.so when it should be the 
undecorated version of them e.g., Mylib (Line 904 in qt4androidtarget.cpp)

This merge request also comes with a merge of few changes in 
qlands-AndroidLighthouse to support extra libraries in the apk.

PD
I am also working on assets support in Creator and the necessary changes 
in QT using JNI. I could send you something very soon if you fancy.
