Integrate Develop branch

Integrate Develop branch

To be more generic and configurable

...and reviewed some details

It seems there are some platform-dependant issues

mingw32 libraries provided were compiled with a different GCC version
(different computer) and seemed to be incompatible on linkage (missing
symbols).

- Removed useless templates
- Reviewed all Makefiles
- Rework some code for Android support
- Added resources to advance template

Fix warning about unsequenced modification of variable

Variable t was read and modified without interleaving sequence points,
technically undefined behavior. Report by Clang's -Wunsequenced

Add Travis CI integration

Also adds commented-out deployment on tag specification
(push build artifacts to Github releases page).
