fixed bug allowing user to export specified rows of reads table
Changelog and dxR version update for v0.52.1
PTFM-7878 dx-build-app syntax check improvements.

Errors in files in the resources/ directory (as opposed to the entry
point file) are now warnings rather than the errors.

The --no-check-syntax flag was added to make even errors in the entry
point file non-fatal.
Propagate --no-check-syntax into remote build.
