Timers' text objects should be explicitly sized to avoid overlap.

[alphaONE2]

At the moment, if the names are sufficiently long, buff names will overlap the time remaining. This makes it very hard to read and use.

To fix this, the name text objects should have their horizontal size set explicitly (feature added in 4.1), so that they clip instead of being allowed to overlap other objects.

Implemented, will now crop the text after a certain length. May add an option to extend the bars to match the text in the future. See #281 .
