Purpose
=======
Fix the inline input fields which width seems broken
because of the new always edit mode.

Specifications
===========
Web :
Introduce new css classes to be added to the
input fields in order to constraint their width and avoid
white gaps in forms.

Event :
Limit the size of the confirmed attendees input
field in the event form and event type form to
display the confirmed attendees message in one line.
When using the debug mode, in the event templates,
inline the Register Button with its checkbox to avoid
line breaks.

Mail :
Limit the size of the delay count input
field in the activity type form and restore the
inline display of the schedule message to
avoid unnecessary white gaps.

CRM :
Fix the leads generation form inlined inputs
display by reducing the inputs width to match
their content display.
Fix the lead form view to align the expected
revenue with the probability for better UI.
Fix the geolocation field and send email button
of the Assigned Partner form tab by restoring
their inline property. Because of the form
grid layout, nested groups had to be used to
correctly restore the display. Alternative solutions
modify the DOM too much, which could lead to more
xpath and inheritance issues.
