Limit max navmeshdb file size

Browse source 
Use "pragma max_page_count" to define max allowed file size in combination with
"pragma page_size" based on a new setting "max navmeshdb file size".

* Stop navmeshtool on the first db error.
* Disable writes to db in the engine on first "database or disk is full"
  SQLite3 error. There is no special error code for this error.
* Change default "write to navmeshdb" to true.
* Use time intervals for transaction duration instead of number of changes.
