Use branch name as the ÖbEngine version if the branch name uses the format "dev-v\d+(\.\d+){,2}"

[Sygmei]

v1
v2
v1.2
v0.5
v0.5.6

are all valid patterns

Right now, to inject version into ÖbEngine, it uses the last tag, so if you checkout to an older tag / branch, the version will not be correct.

This issue requires two things :

• if the current branch is named dev-vX / dev-vX.Y / dev-vX.Y.Z, use that version number (vX will become vX.0.0, vX.Y will become X.Y.0)
• if the branch is not using the dev-vX.Y.Z pattern, find out if one of the parent branch uses this pattern or use closest defined tag

Here are a few examples :

...
[tag v0.3.0]
|
master
|
[tag v0.4.0]
|
new_branch <= You are here

> Version : 0.4.0

...
[tag v0.3.0]
|
master
|
[tag v0.4.4]
|
v0.5
|
new_branch <= You are here

> Version : 0.5.0

...
[tag v0.3.0]
|
master
|
[tag v0.4.4]
|
v0.5
|
[tag v0.4.9] # I know it does not make sense, just to illustrate
|
new_branch <= You are here
|
[tag v0.6.0]

> Version : 0.4.9
