Several changes have been made:

• Fix arrows to select the month
• Fix header text and colours
• Using the correct signal that is generated from elm regarding calendar header.
• Make today white on a dark grey bg.
• Increasing the spacing between table elements
• Changing the "selected day" background from stripe to blue
• Change "check" icon color from blue towhite
• Expecting one signal for the weekend
• Properly clear weekend state.
• Weekend colours

I had to specify the color, the color class and move
"elm.cit_"#_pos".access" earlier in the parts list.
Apparently, if an invisible part (let's say A) to which other
parts (say B) refers to through rel[12].to fields become visible but
are defined after B, B won't be visible anymore.
Also, I made sure to clean .access when cleaning cit elements.
