* Add debug line for flagging to disable upload validation checks
* Handle Microsoft 'enrichment' of certain documents when stored on Sharepoint
* Handle skip_dir checks when nothing to check against (false positive)
* Update default 'skip_file' to include tmp and lock files generated by LibreOffice
* Update code comments & logging output
* Update readme & default config file
* Update database version due to changing defaults of 'skip_file' which will force a rebuild and use of new skip_file default regex
* Reduce scanning the entire local system in monitor mode for local changes
* Add 'monitor_fullscan_frequency' to set the frequency of performing a full disk scan when in monitor mode
* Use make clean to clean up version, not .PHONY which causes rebuild during 'make install'
* Update build instructions to use 'make clean' before 'make'
* Disable automatic indexing as we specifically create the required indexes
* Tell SQLite to store temporary tables in memory. This will speed up many read operations that rely on temporary tables, indices, and views.
* Add links & reasoning behind other PRAGMA settings used
* Add new index specifically for driveId & parentId paring
* To force DB schema & index creation, bump DB schema version
* Update handling of skip_dir and skip_file parsing - should only check if the file is excluded if the parent directory is not
* Add another index for selectByPath database queries
* Add new build option to get more DEBUG symbolic information
* Use boolean values rather than on / off values
* Enable auto_vacuum for entry deletes / database cleanup
* Original skip_dir handling expected an explicit match to path to match. With this patch, wildcard matching for any directory matching the path entry will be skipped
* Update makefile so if using 'release' archive to build, the 'version' file is created with the correct version string as .git/HEAD & index is not available.
* Update Travis CI build script to use an LDC version string
* Add 'libxml2' to guest dependencies for AARM64
* Update ARMHF and AARM64 to use different versions of LDC due to due to https://github.com/ldc-developers/ldc/issues/3027
* Add a http 400 response error handler
* If the response uri generates a 400 error, the JSON response will not contain the access_token. Request to re-authenticate
* By moving the UploadSession creation from the constructor to the init function we guarantee that a re-initialization also starts a new UploadSession.
