- removed unnecessary check for loadiine kexploit map which is not required. only kernel_write() is required. now the installer checks if anything was mapped to detect that the kernel exploit was executed already before the launch of the installer.
- added skip of elf files with names that start with '.' or '_' (linux and MAC hidden files) -> Issue #4
