When saving a LINEX type Graph Item, the Line Width value is too restrictive

[cigamit]

Describe the bug
When saving a LINEX Graph Item within a Graph Template, the Line width, if changed, must be a decimal with two decimal places of precision, which is too restrictive.

To Reproduce
Steps to reproduce the behavior:

1. Edit a Line Graph Template Item
2. Change the Width to 1.0 instead of 1.00
3. Press Save
4. See error

Expected behavior
Cacti should do the rounding automatically and not force the user to enter both decimals of precision. This may impact non-templated Graphs too.
