As a user I want to upload files, and attach them to a note

The 'new' column in mynotebook table can make problems on some mysql installations. The column has to be removed since the tag-system makes it obsolete anyway.

When php returns an error instead of a valid JSON string it is handled by javascript but a default message is displayed to the user. The same messagebox appears when the errorText variable is set within the JSON object. For this case the message in the errorText variable has to be added to the messagebox

Well, this should be done by now

There can be tags that do not have a note assigned. These tags should be deleted automatically.

Tags like: "simple note", "important note", "cooking recipes" are only possible when the tags are separated by commas.

Steps to reproduce
1. Create or edit a note and insert the following text with the quotes:
"testtext"

2. Save the note. As you see there appear backslasches before the quotes.

3. Edit the note again, and just save it without any changes. there are two more backslahes.

Edit or select a new note, enter some text, and place a "&" inside the text. The text behind & will be removed!

Since I have some larger texts in my private notebook I want to have the possibility to expand/collapse notes.

Requirements:
A tag that is assigned to a lot notes.

Steps:
1. Disable all tags
2. Enable the tag
3. Disable it as fast as possible

Results:
Since the tag is deactivated no note should be visible. But all notes of this tag are displayed.

The reason for this is the follwing:
Everytime a tag is selected a request is sent to the server, processed and sent back. This process takes some time. This time can be from 100ms up to some seconds. Since there is no queue in which the requests are processed, small requests are returned faster.

The problem here is as follows:
The request when disabling a tag is returned much faster than the one that contains all notes to be displayed. So if you select and deselect the tag, both requests are sent. The one with empty content gets returned first, and is displayed, but some time later the request with all notes of the tag is sent back and so this one will be displayed.
