insecure gradlew

[IzzySoft]

in case this project is still maintained: a minor fix would be required to increase build security. F-Droid lint complains:

Found plain HTTP URL for gradle repository:
build/com.coste.syncorg/SyncOrg/build.gradle
repositories {
    maven { url 'http://guardian.github.com/maven/repo-releases' }
gradle build uses plain HTTP URLs for repositories!  This is insecure!

Simply make that an https URL, the target supports that. Thanks!
