Update delete command in script_count_lines
project.html template correction

Problem when counting lines.

These commands are necessary for migration from SourceCode alone to Code+SourceCode+Repository (2 commits before):
+ ALTER TABLE projects_sourcecode DROP COLUMN project_id;
+ ALTER TABLE projects_sourcecode DROP FOREIGN KEY project_id_refs_id_dd0aba77;
Typos in project.html

This typo cancelled the call to the function that automatically asks for the number of lines of the project.
