Trim file names in debug macros

[aleks-f]

Currently, the debug macros use __FILE__; aside from sometimes too long path strings, this macro also embeds full paths into the binary, which may be a concern in some circumstances.

• __FILE__ should be replaced with Debugger::sourceFile, which trims the path and only leaves the file name.

• check the binaries to verify that it works at compile time as intended
