#5 Allow case sensitive project names (with special characters)

[Matthias Ratert]

At the moment (release 1.1) no special charaters are allowed for project names. Also the project name is converted to lower case always. This is due to the implementation that all MySql tables are using the project name as table name.
Implementation proposal: Add a new table (_projects) which will list all the project names. Then just use the ID for the table names.
NOTE: The update function will utilize the main development work as all old projects have to be added to the new projects table and all table names have to be re-named!
